跨平臺的線程代碼
改編自fltk,添加了linux平臺下的Sleep實(shí)現(xiàn),只支持Windows和Linux,分別用vc和gcc編譯,代碼如下:
1 | //threads.h, LGPL |
2 | |
3 | #ifndef Threads_H |
4 | #define Threads_H |
5 | |
6 | #ifdef WIN32 |
7 | |
8 | #include < windows.h > |
9 | #include < process.h > |
10 | |
11 | typedef unsigned long Fl_Thread; |
12 | |
13 | static int fl_create_thread(Fl_Thread& t, void *(*f) (void *), void* p) |
14 | { |
15 | return t = (Fl_Thread)_beginthread((void( __cdecl * )( void * ))f, 0, p); |
16 | } |
17 | |
18 | #else |
19 | |
20 | // Use POSIX threading... |
21 | #include < pthread.h > |
22 | #include < unistd.h > |
23 | |
24 | typedef pthread_t Fl_Thread; |
25 | |
26 | static int fl_create_thread(Fl_Thread& t, void *(*f) (void *), void* p) |
27 | { |
28 | return pthread_create((pthread_t*)&t, 0, f, p); |
29 | } |
30 | |
31 | static void Sleep(unsigned long dwMilliseconds) |
32 | { |
33 | usleep(dwMilliseconds * 1000); |
34 | } |
35 | |
36 | #endif |
37 | |
38 | #endif // !Threads_h |
使用示例:
1 | #include "thread.h" |
2 | ... |
3 | |
4 | static Fl_Thread m_thread; // define |
5 | ... |
6 | |
7 | // thread create |
8 | fl_create_thread(m_thread, thread_fun, 0); |
9 | ... |
10 | |
11 | static void* thread_fun(void *p) |
12 | { |
13 | while (1) { |
14 | ... |
15 | } |
16 | |
17 | return 0; |
18 | } |
