+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),

+.SH NAME
+pthread_equal
+\(em compare thread IDs
+.SH SYNOPSIS
+.LP
+.nf
+#include <pthread.h>
+.P
+int pthread_equal(pthread_t \fIt1\fP, pthread_t \fIt2\fP);
+.fi
+.SH DESCRIPTION
+This function shall compare the thread IDs
+.IR t1
+and
+.IR t2 .
+.SH "RETURN VALUE"
+The
+\fIpthread_equal\fR()
+function shall return a non-zero value if
+.IR t1
+and
+.IR t2
+are equal; otherwise, zero shall be returned.
+.P
+If either
+.IR t1
+or
+.IR t2
+are not valid thread IDs, the behavior is undefined.
+.SH ERRORS
+No errors are defined.
+.P
+The
+\fIpthread_equal\fR()
+function shall not return an error code of
+.BR [EINTR] .
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+None.
+.SH RATIONALE
+Implementations may choose to define a
+thread ID as a structure. This allows additional flexibility and
+robustness over using an
+.BR int .
+For example, a thread ID could include a sequence number that allows
+detection of ``dangling IDs'' (copies of a thread ID that has been
+detached). Since the C language does not support comparison on
+structure types, the
+\fIpthread_equal\fR()
+function is provided to compare thread IDs.
+.SH "FUTURE DIRECTIONS"
+None.
+.SH "SEE ALSO"
