ERR_GET_LIB(3SSL) OpenSSL ERR_GET_LIB(3SSL)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.

Introduction
Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
