NAME

       ERR_remove_thread_state, ERR_remove_state - free a thread's 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 == 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       ERR_remove_state is deprecated and has been replaced by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 identi-
       fied by unsigned long values any argument to this function is ignored.
       Calling ERR_remove_state is equivalent to
       ERR_remove_thread_state(NULL).

RETURN VALUE

       ERR_remove_thread_state and ERR_remove_state() return no value.

       err(3)

HISTORY

       ERR_remove_state() 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'.
