MirOS Manual: ERR_GET_FUNC(3), ERR_GET_LIB(3), ERR_GET_REASON(3)


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 glo-
     bally 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 mac-
     ros.

RETURN VALUES

     The library number, function code and reason code respec-
     tively.

HISTORY

     ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are
     available in all versions of SSLeay and OpenSSL.
