NAME¶
pthread_equal - compare thread IDs
SYNOPSIS¶
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
Compile and link with -pthread.
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¶
Multithreading (see pthreads(7))¶
The
pthread_equal() function is thread-safe.
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.
