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 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.
