thrd_equal()

QNX SDP8.0C Library ReferenceAPIDeveloper

Compare two thread IDs

Synopsis:

#include <threads.h>

int thrd_equal( thrd_t thr0,
                thrd_t thr1 );

Arguments:

thr0, thr1: The thread IDs that you want to compare. You can get the IDs when you call thrd_create() or thrd_current().

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The thrd_equal() function compares the thread IDs of thr0 and thr1. It doesn't check to see if they're valid thread IDs.

Returns:

A nonzero value: The thr0 and thr1 thread IDs are equal.
0: The thread IDs aren't equal.

Classification:

C11


Safety:
Cancellation point	No
Signal handler	Yes
Thread	Yes
