PTHREAD_EQUAL(3) Linux Programmer's Manual PTHREAD_EQUAL(3)
pthread_equal - compare thread IDs
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
Compile and link with -pthread.
The pthread_equal() function compares two thread identifiers.
If the two thread IDs are equal, pthread_equal() returns a
nonzero value; otherwise, it returns 0.
This function always succeeds.
For an explanation of the terms used in this section, see
attributes(7).

POSIX.1-2001, POSIX.1-2008.
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.
