if you view the actual source code implementation of make command there will be no point. Try to learn what its doing, and implement your own program the way you percieve it.

err_get_func
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.
SEE ALSO
err(3), ERR_get_error(3)
HISTORY
ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in all versions of SSLeay and OpenSSL.
