C函数篇(pthread_t结构)

linux下是这样定义的：

在linux的实现中pthread_t被定义为 "unsigned long int",参考http://condor.depaul.edu/glancast/443class/docs/pthreads.html

Windows下这样定义：

 1 /*  
 2  * Generic handle type - intended to extend uniqueness beyond  
 3  * that available with a simple pointer. It should scale for either  
 4  * IA-32 or IA-64.  
 5  */    
 6 typedef struct {    
 7     void * p;                   /* Pointer to actual object */    
 8     unsigned int x;             /* Extra information - reuse count etc */    
 9 } ptw32_handle_t;    
10 typedef ptw32_handle_t pthread_t;
