       The pthread_equal() function compares two thread identifiers.

       This function always succeeds.

       POSIX.1-2001.

       pthread_equal - compare thread IDs

       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.

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