Bert Vermeulen 61136ea603 sr: add new driver API call: scan()
This changes the semantics of the init() call as well. That now only
initializes the driver -- an administrative affair, no hardware gets
touched during this call. It returns a standard SR_OK or SR_ERR* code.

The scan() call does a discovery run for devices it knows, and returns
the number found. It can be called at any time.

Bert Vermeulen 40dda2c3a5 sr: remove unused argument from hardware driver function init()
It was actually used in one way: the session file loaded abused it for
passing in the filename -- something it definitely wasn't intended for.
This now uses the proper way to pass arguments to a driver: the new
SR_HWCAP_SESSIONFILE.

The OLS driver could also use it as an indication of the serial port to
use instead of actively probing all serial ports on the system, but there
wasn't any frontend code that passed in such a parameter, making it
entirely useless. That will soon be handled differently with the new
scan() API call, regardless.

Bert Vermeulen 45c59c8bdd sr: moved sigrok.h so libsigrok/libsigrok.h
All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.

The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.

Uwe Hermann 3cd3a20b35 sr: More callback param renames.
Start/stop acquisition callbacks: Consistently name the 'void *' parameter
cb_data for now. The per-device-instance device pointer is called
'session_dev_id' everywhere for now, but this should be renamed to
something more clear.

Uwe Hermann 133a37bfba Use g_try_malloc/g_free/g_strdup consistently.
Avoid plain malloc()/free() in sr/srd, especially in the API calls.
Also avoid g_malloc*() in favor of g_try_malloc*().

Use g_strdup() instead of strdup() so that we can use g_free()
consistently everywhere.

Exceptions: Stuff that is allocated via other libs (not using glib),
should also be properly free'd using the respective free-ing function
(instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc.

Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is
meant for non-fatal/uncritical warnings.

Uwe Hermann 5c64390e5a sr/cli/gtk: Remove analog left-overs from API.
This will come back in some form or another later, but for now
don't clutter the API with non-working stuff. Removing stuff from APIs
is not possible without breaking the API, adding stuff later is simpler.

Uwe Hermann ca070ed9a0 sr: Make more symbols private via static/SR_PRIV.

 - Remove unused GL_* error code #defines.

Uwe Hermann 69890f7399 sr: Eliminate usb/serial instances from API.
The API should be generic and only provide sr_device_instance_new() and
friends, but not sr_usb_device_instance_new(), sr_serial_device_instance_new(),
or others for other device types we may have in the future. The
frontends shouldn't have to know or care about this implementation detail.

This also fixes the problem that parts of sigrok.h contained
'#ifdef HAVE_LIBUSB_1_0' and such, which is even less desirable for the API.

The usb/serial instance specifics are now private, and each driver that
needs them keeps a pointer in its driver-specific context.

Uwe Hermann b7f09cf86d libsigrok: Fix #includes.
In the lib, we should only #include "sigrok.h" or "sigrok-internal.h",
but not the (possibly installed and thus different/older versions) via
<sigrok.h> or <sigrok-internal.h>.

Frontends should of course use <sigrok.h> and <sigrok-internal.h>.

Uwe Hermann cb93f8a927 Other method to avoid "unused var" compiler warnings.
The '(void)varname' method is nicer than 'varname = varname' and also
prevents warnings when compiling sigrok with clang instead of gcc.

Uwe Hermann 697785d1ae libsigrok: closedev() now has a return code.
This is useful to allow frontends to react upon close failures in a
way they see fit (e.g. a popup in the GUI, or error message in the CLI).
They can also still ignore the error if they want, of course.

Uwe Hermann c0a4b9716d ols: Always use glib's memory allocation functions. 2011-04-19 00:18:05 +02:00
Uwe Hermann b53738baf7 Replace g_malloc{0,} with g_try_malloc{0,}.
The g_malloc()/g_malloc0() versions exit/segfault if not enough memory
is available, which is not a good thing in libsigrok.

Instead, we use the g_try_malloc()/g_try_malloc0() variants, which
return NULL if not enough memory is available, so that the caller can
handle the error properly.

Uwe Hermann b08024a836 libsigrok: Introduce sr_dbg/sr_info/sr_warn/sr_err.
We should use these (internal) functions in libsigrok exclusively from
now on, i.e. no more use of glib's g_debug() etc.

These functions are only for libsigrok, the frontends use whatever
logging mechanism is suitable there.

Uwe Hermann 340f6e7aea Fix out-of-tree build.
Use libtool "noinst" local helper libs and use one Makefile.am per
subdir, which is the usual/preferred method. These helper libraries are
purely local and will not be installed.

This also fixes out-of-tree builds of sigrok, i.e. building in a
directory other than the sigrok source directory, e.g.

 $ cd /home/user
 $ git clone ...sigrok
 $ cd sigrok
 $ ./autogen.sh
 $ mkdir /tmp/foo
 $ cd /tmp/foo
 $ /home/user/sigrok/configure
 $ make
 $ make install

This will place all build results (.o files, .la files, etc) in the
local build directory (/tmp/foo) instead of the source directory
(/home/user/sigrok in this example). The installation directory is
selected via the --prefix configure option (/usr/local per default).
