PTHREAD_TESTCANCEL(3) Linux Programmer's Manual PTHREAD_TESTCANCEL(3)
NAME
pthread_testcancel - request delivery of any pending cancellation request
//请求交付任何未决的 cancellation 请求
SYNOPSIS
#include
void pthread_testcancel(void);
Compile and link with -pthread.
DESCRIPTION
Calling pthread_testcancel() creates a cancellation point within the calling thread, so that a thread that is otherwise executing code that contains no
cancellation points will respond to a cancellation request.
//调用 pthread_testcancel() 会在调用线程中创建一个取消点，
//以便执行不包含取消点的代码的线程将对取消请求做出响应。
If cancelability is disabled (using pthread_setcancelstate(3)), or no cancellation request is pending, then a call to pthread_testcancel() has no effect.
//如果可取消性被禁用（使用 pthread_setcancelstate(3)），
//或者没有取消请求处于挂起状态，则调用 pthread_testcancel() 无效。
RETURN VALUE
This function does not return a value. If the calling thread is canceled as a consequence of a call to this function, then the function does not return.
//此函数不返回值。 如果调用线程由于调用此函数而被取消，则该函数不会返回。
ERRORS
This function always succeeds.
//这个函数总是成功的。
