5ERR_remove_thread_state, ERR_remove_state - free a thread's error queue
6
7=head1 SYNOPSIS
8
9 #include <openssl/err.h>
10
11 void ERR_remove_thread_state(const CRYPTO_THREADID *tid);
12
13Deprecated:
14
15 void ERR_remove_state(unsigned long pid);
16
17=head1 DESCRIPTION
18
19ERR_remove_thread_state() frees the error queue associated with thread B<tid>.
20If B<tid> == B<NULL>, the current thread will have its error queue removed.
21
22Since error queue data structures are allocated automatically for new
23threads, they must be freed when threads are terminated in order to
24avoid memory leaks.
25
26ERR_remove_state is deprecated and has been replaced by
27ERR_remove_thread_state. Since threads in OpenSSL are no longer identified
28by unsigned long values any argument to this function is ignored. Calling
29ERR_remove_state is equivalent to B<ERR_remove_thread_state(NULL)>.
30
31=head1 RETURN VALUE
32
33ERR_remove_thread_state and ERR_remove_state() return no value.

39=head1 HISTORY
40
41ERR_remove_state() is available in all versions of SSLeay and OpenSSL. It
42was deprecated in OpenSSL 1.0.0 when ERR_remove_thread_state was introduced
43and thread IDs were introduced to identify threads instead of 'unsigned long'.
