Hi
i have the following structure
struct S
{
char Mod_num;
char val;
char chr_nm_cd;
}
I am reading a 2GB file and inserting into the structure and writing into a vector.
I feel like only vector will be a right option. I tried with multimap but it is memory intensive and hence i... (1 Reply)

err_get_lib
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.
