ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library,
function and reason code
#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);
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.
The library number, function code and reason code respectively.
err(3), ERR_get_error(3)
ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are
available in all versions of SSLeay and OpenSSL.
