ERR_GET_LIB(3openssl) OpenSSL ERR_GET_LIB(3openssl) 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.
