* w32pthreads: always use Vista+ API, drop XP supportwm42017-12-261-256/+10
| | | | | | | | | | | This removes the XP compatibility code, and switches entirely to SWR locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore. It was decided in a project vote that this is OK.
* Support building C++ files with MSVCAaron Levinson2017-04-131-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Made appropriate changes to be able to successfully build C++ files using a Visual C++ build on Windows. Based on an earlier patch by Kyle Schwarz. Comments: -- compat/w32pthreads.h: Made appropriate changes to w32pthreads.h to get it to build when it is being included in a C++ file and built with Visual C++. This is mostly a copy of Kyle Schwarz's patch as described above. -- configure: a) Now calling set_ccvars CXX to cause the various CXX_ variables to be setup properly. For example, with MSVC (Microsoft Visual C++), this causes CXX_O to be set to -Fo$@ instead of using the default value. The default value does not work with Visual C++. This change will also have the impact of correcting CXX_O (and possibly CXX_C) for other compilers, although this is really only relevant for the Intel compiler, in addition to MSVC. b) Now using cl for the C++ compiler for the MSVC toolchain. This is currently only relevant for building the Blackmagic/Decklink-related files under avdevice. Signed-off-by: Hendrik Leppkes <h.leppkes@gmail.com>

| * w32pthreads: Mark functions in compatibility wrapper as av_unusedDiego Biurrun2014-08-151-10/+11
| | | | | | | | | | | | This avoids annoying warnings about unused functions. The compatibility wrapper is designed to provide a complete (stub) API, so some functions being unused by some files is natural and no reason for a warning.

| * w32threads: Use newer thread synchronization functions when targeting VistaMartin Storsjö2014-08-131-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When explicitly targeting Vista or newer (which only happens if the caller explicitly sets _WIN32_WINNT to a high enough value via the extra cflags option - otherwise configure script sets -D_WIN32_WINNT=0x0502), we already unconditionally link to the ConditionVariable functions, since 4622f11f9. Similarly use the newer -Ex versions of CreateEvent, CreateSemaphore, InitializeCriticalSection and WaitForSingleObject, that all appeared in Vista. When building Windows Store applications, the older versions of these functions aren't available, only the -Ex functions. When doing such a build, the user can set -D_WIN32_WINNT=0x0600 to forcibly use the newer functions instead. Signed-off-by: Martin Storsjö <martin@martin.st>

The compiler should be able to do the dead code elimination now without this when the cond_* names point directly to the real functions instead of to local function pointers.

| | | | | | | | | | | | | | | | | | | | | | | | This reduces the call overhead slightly. More noticeably, it restores the earlier (unintended?) feature that condition variable functions work just fine even if w32thread_init() hasn't been called. This was broken as a side effect of 4622f11f9, if explicitly targeting Vista+. This makes w32threading work in VP8 again, if targeting Vista+. Signed-off-by: Martin Storsjö <martin@martin.st>
