This header file's only // purpose is so we can write portable demo programs. It may be useful // or an inspiration to people who want to try writing multithreaded // programs themselves. // // FLTK has no multithreaded support unless the main thread calls Fl::lock(). // This main thread is the only thread allowed to call Fl::run() or Fl::wait(). // From then on FLTK will be locked except when the main thread is actually // waiting for events from the user. Other threads must call Fl::lock() and // Fl::unlock() to surround calls to FLTK (such as to change widgets or // redraw them). #ifndef Threads_H # define Threads_H # ifdef HAVE_PTHREAD_H // Use POSIX threading... # include <pthread.h> typedef pthread_t Fl_Thread; extern "C" { typedef void *(Fl_Thread_Func)(void *); } static int fl_create_thread(Fl_Thread& t, Fl_Thread_Func* f, void* p) { return pthread_create((pthread_t*)&t, 0, f, p); } # elif defined(WIN32) && !defined(__WATCOMC__) // Use Windows threading... # include <windows.h> # include <process.h> typedef unsigned long Fl_Thread; extern "C" { typedef void *(__cdecl Fl_Thread_Func)(void *); } static int fl_create_thread(Fl_Thread& t, Fl_Thread_Func* f, void* p) { return t = (Fl_Thread)_beginthread((void( __cdecl * )( void * ))f, 0, p); } # elif defined(__WATCOMC__) # include <process.h> typedef unsigned long Fl_Thread; extern "C" { typedef void *(__cdecl Fl_Thread_Func)(void *); } static int fl_create_thread(Fl_Thread& t, Fl_Thread_Func* f, void* p) { return t = (Fl_Thread)_beginthread((void(* )( void * ))f, 32000, p); } # endif // !HAVE_PTHREAD_H #endif // !Threads_h // // End of "$Id$". //
