PTHREAD_TESTCANCEL(3) Linux Programmer's Manual PTHREAD_TESTCANCEL(3)NAME
pthread_testcancel - request delivery of any pending cancellation request
SYNOPSIS
#include <pthread.h>
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.
If cancelability is disabled (using pthread_setcancelstate(3)), or no cancellation request is pending, then a call to pthread_cancel() has
no effect.
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.
ERRORS
This function always succeeds.
CONFORMING TO
POSIX.1-2001.
EXAMPLE
See pthread_cleanup_push(3).

Hello!
First of all, sorry for my English, I'm not a native English speaker.
I know, that printf() function uses write() function. "man cancellation" says that write() function is a cancellation point. But when I call pthread_cancel() for my thread, which calls printf() in infinite cycle, it... (4 Replies)
I tried to execute a sample pthread program to cancel a newly created one using pthread_cancel(). but using valgrind on my code shows some memory leak.
My Code:
#include "iostream"
#include "unistd.h"
#include "pthread.h"
#include "signal.h"
using namespace std;
void handler(int);
