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 non-zero value;
       otherwise, it returns 0.

ERRORS         top

       This function always succeeds.

CONFORMING TO         top

       POSIX.1-2001.

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.
