Threads Library (libpthreads.a)
#include <pthread.h>
int pthread_equal (pthread_t t1, pthread_t t2);
The pthread_equal subroutine compares the thread IDs thread1 and thread2. Since the thread IDs are opaque objects, it should not be assumed that they can be compared using the equality operator (==).
Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.
| thread1 | Specifies the first ID to be compared. |
| thread2 | Specifies the second ID to be compared. |
The pthread_equal function returns a non-zero value if t1 and t2 are equal; otherwise, zero is returned.
If either t1 or t2 are not valid thread IDs, the behaviour is undefined.
This subroutine is part of the Base Operating System (BOS) Runtime.
The pthread_self (pthread_self Subroutine) subroutine, the pthread_create (pthread_create Subroutine) subroutine, the pthread.h file.
