\&\fIERR_remove_thread_state()\fR frees the error queue associated with thread \fBtid\fR.
|
|
If \fBtid\fR == \fB\s-1NULL\s0\fR, the current thread will have its error queue removed.
|
|
.PP
|
|
Since error queue data structures are allocated automatically for new
|
|
threads, they must be freed when threads are terminated in order to
|
|
avoid memory leaks.

|
ERR_remove_state is deprecated and has been replaced by
|
|
ERR_remove_thread_state. Since threads in OpenSSL are no longer identified
|
|
by unsigned long values any argument to this function is ignored. Calling
|
|
ERR_remove_state is equivalent to \fBERR_remove_thread_state(\s-1NULL\s0)\fR.

\&\fIERR_remove_state()\fR is available in all versions of SSLeay and OpenSSL. It
|
|
was deprecated in OpenSSL 1.0.0 when ERR_remove_thread_state was introduced
|
|
and thread IDs were introduced to identify threads instead of 'unsigned long'.
