跨平台的线程代码

跨平台的线程代码

改编自fltk，添加了linux平台下的Sleep实现，只支持Windows和Linux，分别用vc和gcc编译，代码如下：

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	}
