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.

*pthread_create*(3), *pthread_self*(3), *pthreads*(7)
