ERR_remove_state(3)          OpenSSL          ERR_remove_state(3)

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     ERR_remove_state is deprecated and has been replaced by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 identified 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.

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'.
