PTHREAD_EQUAL(3)          Linux Programmer's Manual         PTHREAD_EQUAL(3)

NAME         top

       pthread_equal - compare thread IDs

SYNOPSIS         top

       #include <pthread.h>
       int pthread_equal(pthread_t t1, pthread_t t2);
       Compile and link with -pthread.

DESCRIPTION         top

       The pthread_equal() function compares two thread identifiers.

RETURN VALUE         top

       If the two thread IDs are equal, pthread_equal() returns a nonzero
       value; otherwise, it returns 0.

ERRORS         top

       This function always succeeds.

CONFORMING TO         top

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

NOTES         top

       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.
