Hi,
I have initialized SDL library using library function call SDL_Init() and then create a mutex and condition variable.
mutex=SDL_CreateMutex(); //SDL_mutex *mutex;
cond=SDL_CreateCond(); //SDL_cond *cond;
and at the end of program, I am destroying the mutex & conditional variable and shuting down the SDL subsystem as follows:
//--------------
SDL_DestroyMutex(mutex);
SDL_DestroyCond(cond);
SDL_Quit();
//--------------
Call to SDL_DestroyMutex() & SDL_DestroyCond() is successfull but call to SDL_Quit() causing crash.
Can someone please point out why SDL_Quit() is causing crash? Thanks in advance.
Here is the message generated by program at the end.------------------
