In other words, \fBpthread_detach()\fR dynamically resets the \fIdetachstate\fR attribute of the thread to \fBPTHREAD_CREATE_DETACHED.\fR After a successful call to this function, it would not be necessary to reclaim the thread using \fBpthread_join()\fR. See \fBpthread_join\fR(3C). If \fIthread\fR has not terminated, \fBpthread_detach()\fR will not cause it to terminate. The effect of multiple \fBpthread_detach()\fR calls on the same target thread is unspecified. .SH RETURN VALUES .sp .LP If successful, \fBpthread_detach()\fR returns \fB0\fR. Otherwise, an error number is returned to indicate the error. .SH ERRORS .sp .LP The \fBpthread_detach()\fR function will fail if: .sp .ne 2 .na \fB\fBEINVAL\fR\fR .ad .RS 10n The implementation has detected that the value specified by \fIthread\fR does not refer to a joinable thread. .RE .sp .ne 2 .na \fB\fBESRCH\fR\fR .ad .RS 10n No thread could be found corresponding to that specified by the given thread \fBID.\fR .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
