ERR_GET_LIB(3)                      OpenSSL                     ERR_GET_LIB(3)

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
       number, 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.
