 Doxygen
 -------
 - Use the @ notation for all Doxygen comments (e.g. @param, not \param).
 - Do not use the @brief tag, it's unnecessary as we use JAVADOC_AUTOBRIEF.
 - Generally use the following item order in Doxygen comments:
    - Brief function description (1 line), followed by an empty line.
    - Optionally, a longer function description (and another empty line).
    - The list of parameter descriptions (@param).
    - The return value description (@return or @retval).
    - An optional @since tag (only for public SR_API functions).
    - An optional @private tag (for private SR_PRIV functions).
 - In @param lines, the name of the parameter is followed by a space and
   then a sentence describing the parameter (starts with a capital letter,
   ends with a full stop).
 - In Doxygen comments, put an empty line between the block of @param lines
   and the final @return line. The @param lines themselves (if there is more
   than one) are not separated by empty lines.
 - Mark private functions (SR_PRIV) with /** @private */, so that Doxygen
   doesn't include them in the output. Functions that are "static" anyway
-   don't need to be marked like this. Functions in non-public files that

   Don't use @internal, always use @private instead.

   Variables that are "static" don't need to be marked like this.

 as well when they communicate by means of RFCOMM channels, or one of the

+The use of a kernel module also means it is dependent on the kernel version
 used, as well as on whether this specific module is available in the kernel.
 Additionally, the usbtmc kernel module has been known to have various bugs
 in some versions. These are some (but not all) drawbacks of using a kernel
 module as opposed to a libusb-based driver that works in user-space.
 We plan to change the driver to use the 'librevisa' user-space shared
 library (which uses libusb) soon, which will fix all these issues and make
 the driver portable at the same time.
 Mooshimeter
 -----------
 The Mooshim Engineering Mooshimeter is controlled via Bluetooth Low Energy
 (sometimes called Bluetooth 4.0), as such it requires a supported Bluetooth
 interface available. The 'conn' option is required and must contain the
 Bluetooth MAC address of the meter.
 Example:
  $ sigrok-cli --driver mooshimeter-dmm:conn=12-34-56-78-9A-BC ...
 Since the Mooshimeter has no physical interface on the meter itself, the
 channel configuration is set with the 'channel_config' option. The format
 of this option is 'CH1,CH2' where each channel configuration has the form
 'MODE:RANGE:ANALYSIS', with later parts being optional. In addition for
 CLI compatibility, the ',' in the channels can also be a '/' and the ':' in
 the individual configuration can be a ';'.
 Available channel 1 modes:
  - Current, A: Current in amps
  - Temperature, T, K: Internal meter temperature in Kelvin
  - Resistance, Ohm, W: Resistance in ohms
  - Diode, D: Diode voltage
  - Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max)
 Available channel 2 modes:
  - Voltage, V: Voltage
  - Temperature, T, K: Internal meter temperature in Kelvin
  - Resistance, Ohm, W: Resistance in ohms
  - Diode, D: Diode voltage
  - Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max)
 Only one channel can use the shared inputs at a time (e.g. if CH1 is measuring
 resistance, CH2 cannot measure low voltage). Temperature is excepted from
 this, so the meter can measure internal temperature and low voltage at the
 same time.
 Additionally, the meter can calculate the real power of both channels. This
 generally only makes sense when CH1 is set to current and CH2 is set to a
 voltage and so it is disabled by default. It must be enabled by enabling the
 'P' channel (the third channel).
 The range of the channel specification sets the maximum input for that channel
 and is rounded up to the next value the meter itself supports. For example,
 specifying 50 for the voltage will result in the actual maximum of 60.
 Specifying 61 would result in 600. If omitted, sigrok will perform
 auto-ranging of the channel by selecting the next greater value than the
 latest maximum.
 The analysis option sets how the meter reports its internal sampling buffer
 to sigrok:
 - Mean, DC: The default is a simple arithmetic mean of the sample buffer
 - RMS, AC: The root mean square of the sample buffer
 - Buf, Buffer, Samples: Report the entire sample buffer to sigrok. This
   results in packets that contain all the samples in the buffer instead
   of a single output value.
 The size of the sample buffer is set with the 'avg_samples' option, while
 the sampling rate is set with the 'samplerate' option. So the update rate
 is avg_samples/samplerate. Both are rounded up to the next supported value
 by the meter.
 Example:
  $ sigrok-cli -c channel_config="Aux;0.1/T" --driver mooshimeter-dmm...
  $ sigrok-cli -c channel_config="A;;AC/V;;AC" --driver mooshimeter-dmm...

 * Initializing and shutting down libsigrok.
 *
 * Before using any of the libsigrok functionality, sr_init() must
 * be called to initialize the library, which will return a struct sr_context
 * when the initialization was successful.
 *
 * When libsigrok functionality is no longer needed, sr_exit() should be
 * called, which will (among other things) free the struct sr_context.
 *
 * Example for a minimal program using libsigrok:
 *
 * @code{.c}
 *   #include <stdio.h>
 *   #include <libsigrok/libsigrok.h>
 *
 *   int main(int argc, char **argv)
 *   {

 *   	struct sr_context *sr_ctx;
 *
 *   	if ((ret = sr_init(&sr_ctx)) != SR_OK) {
 *   		printf("Error initializing libsigrok (%s): %s.",
 *   		       sr_strerror_name(ret), sr_strerror(ret));
 *   		return 1;

 /**
 * @mainpage API Reference
 *
 * Introduction
 * ------------
 *
 * The sigrok-java API provides an object-oriented Java interface to the
 * functionality in libsigrok. It is built on top of the libsigrokcxx C++ API.
 *
 * Getting started
 * ---------------
 *
 * Usage of the sigrok-java API needs to begin with a call to Context.create().
 * This will create the global libsigrok context and returns a Context object.
 * Methods on this object provide access to the hardware drivers, input and
 * output formats supported by the library, as well as means of creating other
 * objects such as sessions and triggers.
 *
 * Error handling
 * --------------
 *
 * When any libsigrok C API call returns an error, an Error exception is raised,
 * which provides access to the error code and description.

 "@mainpage API Reference
 Introduction
 ------------
 The pysigrok API provides an object-oriented Python interface to the
 functionality in libsigrok. It is built on top of the libsigrokcxx C++ API.
 Getting started
 ---------------
 Usage of the pysigrok API needs to begin with a call to Context.create().
 This will create the global libsigrok context and returns a Context object.
 Methods on this object provide access to the hardware drivers, input and output
 formats supported by the library, as well as means of creating other objects
 such as sessions and triggers.
 Error handling
 --------------
 When any libsigrok C API call returns an error, an Error exception is raised,
 which provides access to the error code and description."

 "
 = Introduction
 The sigrok Ruby API provides an object-oriented Ruby interface to the
 functionality in libsigrok. It is built on top of the libsigrokcxx C++ API.
 = Getting started
 Usage of the sigrok Ruby API needs to begin with a call to Context.create().
 This will create the global libsigrok context and returns a Context object.
 Methods on this object provide access to the hardware drivers, input and output
 formats supported by the library, as well as means of creating other objects
 such as sessions and triggers.
 = Error handling
 When any libsigrok C API call returns an error, an Error exception is raised,
 which provides access to the error code and description."

 /**
 * Remove unused probes from samples.
 *
 * Convert sample from maximum probes -- the way the hardware driver sent
 * it -- to a sample taking up only as much space as required, with
 * unused probes removed.
 *
 * The "unit size" is the number of bytes used to store probe values.
 * For example, a unit size of 1 means one byte is used (which can store
 * 8 probe values, each of them is 1 bit). A unit size of 2 means we can
 * store 16 probe values, 3 means we can store 24 probe values, and so on.
 *
 * If the data coming from the logic analyzer has a unit size of 4 for
 * example (as the device has 32 probes), but only 2 of them are actually
 * used in an acquisition, this function can convert the samples to only
 * use up 1 byte per sample (unit size = 1) instead of 4 bytes per sample.
 *
 * The output will contain the probe values in the order specified via the
 * probelist. For example, if in_unitsize = 4, probelist = [5, 16, 30], and
 * out_unitsize = 1, then the output samples (each of them one byte in size)
 * will have the following format: bit 0 = value of probe 5, bit 1 = value
 * of probe 16, bit 2 = value of probe 30. Unused bit(s) in the output byte(s)
 * are zero.
 *
 * The caller must make sure that length_in is not bigger than the memory
 * actually allocated for the input data (data_in), as this function does
 * not check that.
 *
 * @param in_unitsize The unit size (>= 1) of the input (data_in).
 * @param out_unitsize The unit size (>= 1) the output shall have (data_out).
 *                     The requested unit size must be big enough to hold as
 *                     much data as is specified by the number of enabled
 *                     probes in 'probelist'.
 * @param probe_array Pointer to a list of probe numbers, numbered starting
 *                    from 0. The list is terminated with -1.
 * @param data_in Pointer to the input data buffer. Must not be NULL.
 * @param length_in The input data length (>= 1), in number of bytes.
 * @param data_out Variable which will point to the newly allocated buffer
 *                 of output data. The caller is responsible for g_free()'ing
 *                 the buffer when it's no longer needed. Must not be NULL.
 * @param length_out Pointer to the variable which will contain the output
 *                   data length (in number of bytes) when the function
 *                   returns SR_OK. Must not be NULL.
 *
 * @return SR_OK upon success, SR_ERR_MALLOC upon memory allocation errors,
 *         or SR_ERR_ARG upon invalid arguments.
 *         If something other than SR_OK is returned, the values of
 *         out_unitsize, data_out, and length_out are undefined.
