   **int pthread_equal(pthread_t** _t1_**, pthread_t** _t2_**);**

DESCRIPTION top

   The **pthread_equal**() function compares two thread identifiers.

RETURN VALUE top

STANDARDS top

   POSIX.1-2008.

HISTORY 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 _pthreadt_ values.
