#include <sys/types.h> pid_t gettid(void); |
描述
gettid() returns the thread ID of the current process. This is equal to the process ID (as returned by getpid(2)), unless the process is part of a thread group (created by specifying the CLONE_THREAD flag to the clone(2) system call). All processes in the same thread group have the same PID, but each one has a unique TID.返回值
如果成功,返回当前进程的线程ID。错误
这个调用永远是成功的。遵循于
gettid() 是Linux特有的,并应在该旨在是可移植的程序不被使用。注意
