NAME

pthread_equal - compare thread IDs

int pthread_equal(pthread_t t1 , pthread_t t2 );

DESCRIPTION

The pthread_equal () function compares two thread identifiers.

STANDARDS

POSIX.1-2008.

HISTORY

POSIX.1-2001.

NOTES

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.
