pthread_equal(3)        Library Functions Manual        pthread_equal(3)

NAME         top

       pthread_equal - compare thread IDs

LIBRARY         top

       POSIX threads library (libpthread, -lpthread)

SYNOPSIS         top

       #include <pthread.h>

       int pthread_equal(pthread_t t1, pthread_t t2);

DESCRIPTION         top

       The pthread_equal() function compares two thread identifiers.

RETURN VALUE         top

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

ERRORS         top

       This function always succeeds.

STANDARDS         top

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 pthread_t values.
