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161 ERR_remove_state is deprecated and has been replaced by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