ERR_remove_state(3) OpenSSL ERR_remove_state(3)NAME
ERR_remove_state - free a thread's error queue
void ERR_remove_state(unsigned long pid);
ERR_remove_state() frees the error queue associated with thread pid. If pid == 0, 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() returns no value.
SEE ALSO err(3)HISTORY
ERR_remove_state() is available in all versions of SSLeay and OpenSSL.

ERR_get_error() returns the earliest error code from the thread's error queue and removes the entry. This function can be called repeatedly
until there are no more error codes to return.
ERR_peek_error() returns the earliest error code from the thread's error queue without modifying it.
ERR_peek_last_error() returns the latest error code from the thread's error queue without modifying it.
See ERR_GET_LIB(3) for obtaining information about location and reason of the error, and ERR_error_string(3) for human-readable error
ERR_get_error_line(), ERR_peek_error_line() and ERR_peek_last_error_line() are the same as the above, but they additionally store the file
name and line number where the error occurred in *file and *line, unless these are NULL.
ERR_get_error_line_data(), ERR_peek_error_line_data() and ERR_get_last_error_line_data() store additional data and flags associated with
the error code in *data and *flags, unless these are NULL. *data contains a string if *flags&ERR_TXT_STRING. If it has been allocated by
OPENSSL_malloc(), *flags&ERR_TXT_MALLOCED is true.
The error code, or 0 if there is no error in the queue.
