142 ERR_remove_thread_state, ERR_remove_state \- free a thread's error queue
144 .IX Header "SYNOPSIS"
146 \& #include <openssl/err.h>
148 \& void ERR_remove_thread_state(const CRYPTO_THREADID *tid);
154 \& void ERR_remove_state(unsigned long pid);
157 .IX Header "DESCRIPTION"
158 \&\fIERR_remove_thread_state()\fR frees the error queue associated with thread \fBtid\fR.
159 If \fBtid\fR == \fB\s-1NULL\s0\fR, the current thread will have its error queue removed.
161 Since error queue data structures are allocated automatically for new
162 threads, they must be freed when threads are terminated in order to
165 ERR_remove_state is deprecated and has been replaced by
166 ERR_remove_thread_state. Since threads in OpenSSL are no longer identified
167 by unsigned long values any argument to this function is ignored. Calling
168 ERR_remove_state is equivalent to \fBERR_remove_thread_state(\s-1NULL\s0)\fR.
170 .IX Header "RETURN VALUE"
171 ERR_remove_thread_state and \fIERR_remove_state()\fR return no value.
173 .IX Header "SEE ALSO"
177 \&\fIERR_remove_state()\fR is available in all versions of SSLeay and OpenSSL. It
178 was deprecated in OpenSSL 1.0.0 when ERR_remove_thread_state was introduced
179 and thread IDs were introduced to identify threads instead of 'unsigned long'.
