死鎖是在編寫多執行緒併發時候所需要考慮的問題,在多執行緒軟體使用多個互斥鎖來保護共享資源時,如果設計不合理會出現多個鎖相互巢狀並且都在等待彼此的鎖被釋放,這樣就會出現死鎖現象,讓系統掛起一直相互等待下去。下面給個例子說明這一現象:
/* 標頭檔案 */
#include #include #include #include #include pthread_mutex_t mutex_one,mutex_two;
pthread_mutex_t mutex;
pthread_cond_t cond;
void *thread_routine_one(void *arg)
void *thread_routine_two(void *arg)
void main()
