NAME

ERR_remove_thread_state, ERR_remove_state — free a thread's OpenSSL error queue

SYNOPSIS

#include <openssl/err.h>

void
ERR_remove_thread_state(const CRYPTO_THREADID *tid);

Deprecated:

void
ERR_remove_state(unsigned long pid);

DESCRIPTION

ERR_remove_thread_state() frees the error queue associated with thread tid. If tid is NULL, the current thread will have its error queue removed.

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ERR_remove_state() is deprecated and has been replaced by ERR_remove_thread_state().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 ERR_remove_thread_state(NULL).

HISTORY

ERR_remove_state() first appeared in SSLeay 0.6.1 and has been available since OpenBSD 2.4.

It was deprecated in OpenSSL 1.0.0 and OpenBSD 4.9 when ERR_remove_thread_state() was introduced and thread IDs were introduced to identify threads instead of unsigned long.
