14 int ERR_GET_FUNC(unsigned long e);
16 int ERR_GET_REASON(unsigned long e);
18 int ERR_FATAL_ERROR(unsigned long e);
22 The error code returned by ERR_get_error() consists of a library
23 number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC()
24 and ERR_GET_REASON() can be used to extract these.
26 ERR_FATAL_ERROR() indicates whether a given error code is a fatal error.
28 The library number and function code describe where the error
29 occurred, the reason code is the information about what went wrong.
31 Each sub-library of OpenSSL has a unique library number; function and
32 reason codes are unique within each sub-library. Note that different
33 libraries may use the same value to signal different functions and
36 B<ERR_R_...> reason codes such as B<ERR_R_MALLOC_FAILURE> are globally
37 unique. However, when checking for sub-library specific reason codes,
38 be sure to also compare the library number.
40 ERR_GET_LIB(), ERR_GET_FUNC(), ERR_GET_REASON(), and ERR_FATAL_ERROR()
45 The library number, function code, reason code, and whether the error
46 is fatal, respectively.
54 ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in
55 all versions of OpenSSL.
