Returns the sequence number of a thread
Threads Library (libpthreads.a)
int pthread_getunique_np ( thread, sequence)
The pthread_getunique_np subroutine returns the sequence number of the thread thread. The sequence number is a number, unique to each thread, associated with the thread at creation time.
- 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.
- The pthread_getunique_np subroutine is not portable.
|thread||Specifies the thread.|
|sequence||Points to where the sequence number will be stored.|
Upon successful completion, the sequence number is returned via the sequence parameter, and 0 is returned. Otherwise, an error code is returned.
pthread_getunique_np subroutine is unsuccessful if the following is
|EINVAL||The thread or sequence parameters are not valid.|
|ESRCH||The thread thread does not exist.|
