ERRGETLIB(3) OpenSSL ERRGETLIB(3)

NAME
       ERRGETLIB, ERRGETFUNC, ERRGETREASON - get library, function and
       reason code

SYNOPSIS
        #include 

        int ERRGETLIB(unsigned long e);

        int ERRGETFUNC(unsigned long e);

        int ERRGETREASON(unsigned long e);

DESCRIPTION
       The error code returned by ERRgeterror() consists of a library
       number, function code and reason code. ERRGETLIB(), ERRGETFUNC()
       and ERRGETREASON() 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.

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

       ERRGETLIB(), ERRGETFUNC() and ERRGETREASON() are macros.

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

HISTORY       ERRGETLIB(), ERRGETFUNC() and ERRGETREASON() are available in all
       versions of SSLeay and OpenSSL.
