NAME
       ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and
       reason code

SYNOPSIS
	#include <openssl/err.h>

	int ERR_GET_LIB(unsigned long e);

	int ERR_GET_FUNC(unsigned long e);

	int ERR_GET_REASON(unsigned long e);

DESCRIPTION
       The error code returned by ERR_get_error() consists of a library num-
       ber, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC() and
       ERR_GET_REASON() can be used to extract these.

       The library number and function code describe where the error
       occurred, the reason code is the information about what went wrong.

       Each sub-library of OpenSSL has a unique library number; function and
       reason codes are unique within each sub-library.	 Note that different
       libraries may use the same value to signal different functions and
       reasons.

       ERR_R_... reason codes such as ERR_R_MALLOC_FAILURE are globally
       unique. However, when checking for sub-library specific reason codes,
       be sure to also compare the library number.

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are macros.

RETURN VALUES
       The library number, function code and reason code respectively.

HISTORY
       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in
       all versions of SSLeay and OpenSSL.
