(sr_dev_driver.config_probe_set): New optional callback enabling
drivers to be notified upon changes to probe settings.
(sr_dev_probe_enable, sr_dev_trigger_set): Invoke new driver
callback on changes.
(sr_dev_driver.config_commit): New optional callback allowing
drivers to defer application of configuration settings until
an explicit call to config_commit().
(sr_config_commit): New public wrapper function.
Most of the supported gear uses the ANSI C locale for communication, and if the
client sets up an incompatible locale parsing would fail.
This function ignores the client's locale and parses floating point numbers
using the ANSI C locale. This function should be always used when parsing
floating point numbers coming from the instrument.
This patch adds a function for a common operation of all serial based drivers.
It extracts the serial options from the options linked list that is passed down
to every hardware driver.
This patch adds a function to read and parse a SCPI response which contains a
comma separated list of unsignet 8-bit integer numbers (e.g "1,0,64").
This is particularly useful if the instrument sends digital measurement data
in this format.
This patch adds a function to read and parse a SCPI response which contains a
comma-separated list of floating-point numbers (e.g. "1.0e-5,2.0e-4,3.0e-3").
This is particularly useful if the instrument sends analog measurement
data in this format.
The SCPI standard specifies the "*OPC?" command (Operation complete query) which
queries the instrument for its operative state. When all pending operations are
complete, the instrument responds with a "1".
Some manufacturers block before completing all operations and don't respond
with anything and some of them respond with a "0". This function handles both
cases uniformly.
This patch adds helper functions to read an SCPI response and parse the response
as an integer, boolean, floating-point or double-precision floating-point number.
The Standard Commands for Programmable Instruments (SCPI) defines a standard
for syntax and commands to use in controlling programmable test and measurement
devices.

This patch adds helper functions for sending SCPI commands, reading a SCPI
response and reading and parsing a SCPI "*IDN?" response.
The fields of this structure should not be used directly by frontends
(and none of the current ones do). Thus, make the struct opaque and hide
its contents from the API.
Disable drivers that need serial port support if libserialport is not found.
Also, disable building various other serial port related code in that case.
FreeBSD's libusb-1.0 compatible library has a few differences compared
to the "normal" libusb-1.0 from libusb.org which we have to work around.
LIBUSB_CLASS_APPLICATION doesn't exist in FreeBSD's libusb, and
libusb_handle_events_timeout_completed() doesn't exist either.
The latter is basically libusb_handle_events_timeout() with an extra
(unused by us) parameter, so the workaround is relatively simple.
This fixes bug #185.
