C函數篇(pthread_t結構)

linux下是這樣定義的：

在linux的實現中pthread_t被定義爲 "unsigned long int",參考http://condor.depaul.edu/glancast/443class/docs/pthreads.html

Windows下這樣定義：

 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;
