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 

        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 respec-
       tively.

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