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


LIBRARY

       libcrypto, -lcrypto


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 rea-
       sons.

       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.
