Ryan C. Gordon 228219dcd4 include: Improved SDL_GetTicks*() documentation a little. 2021-11-01 14:28:00 -04:00
Ryan C. Gordon 99c9727dc0 timer: Added SDL_GetTicks64(), for a timer that doesn't wrap every ~49 days. 
Note that this removes the timeGetTime() fallback on Windows; it is a
32-bit counter and SDL2 should never choose to use it, as it only is needed
if QueryPerformanceCounter() isn't available, and QPC is _always_ available
on Windows XP and later.

OS/2 has a similar situation, but since it isn't clear to me that similar
promises can be made about DosTmrQueryTime() even in modern times, I decided
to leave the fallback in, with some heroic measures added to try to provide a
true 64-bit tick counter despite the 49-day wraparound. That approach can
migrate to Windows too, if we discover some truly broken install that doesn't
have QPC and still depends on timeGetTime().

Fixes #4870.

Philipp Wiesemann 2fa0394855 Corrected documentation of SDL_AddTimer() in header file. 2015-08-19 22:29:37 +02:00
Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later. 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
