NAME¶
pthread_equal - compare thread IDs
LIBRARY¶
POSIX threads library (libpthread, -lpthread)
SYNOPSIS¶
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
DESCRIPTION¶
The pthread_equal() function compares two thread identifiers.
RETURN VALUE¶
If the two thread IDs are equal, pthread_equal() returns a nonzero value; otherwise, it returns 0.
ERRORS¶
This function always succeeds.
ATTRIBUTES¶
For an explanation of the terms used in this section, see attributes(7).
Interface | Attribute | Value |
pthread_equal () | Thread safety | MT-Safe |
STANDARDS¶
POSIX.1-2008.
HISTORY¶
POSIX.1-2001.
NOTES¶
The pthread_equal() function is necessary because thread IDs should be considered opaque: there is no portable way for applications to directly compare two pthread_t values.
