ERR_GET_LIB(3)			    OpenSSL			ERR_GET_LIB(3)

NAME
       ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON, ERR_FATAL_ERROR - get
       information from	error codes

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);

	int ERR_FATAL_ERROR(unsigned long e);

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

       ERR_FATAL_ERROR() indicates whether a given error code is a fatal
       error.

       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(), ERR_GET_REASON(),	and ERR_FATAL_ERROR()
	are macros.

RETURN VALUES
       The library number, function code, reason code, and whether the error
       is fatal, respectively.

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