=head1 NAME
-ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and
-reason code
+ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON, ERR_FATAL_ERROR
+- get information from error codes
=head1 SYNOPSIS
int ERR_GET_REASON(unsigned long e);
+ int ERR_FATAL_ERROR(unsigned long e);
+
=head1 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.
+ERR_FATAL_ERROR() indicates whether a given error code is a fatal error.
+
The library number and function code describe where the error
occurred, the reason code is the information about what went wrong.
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.
+ERR_GET_LIB(), ERR_GET_FUNC(), ERR_GET_REASON(), and ERR_FATAL_ERROR()
+are macros.
=head1 RETURN VALUES
-The library number, function code and reason code respectively.
+The library number, function code, reason code, and whether the error
+is fatal, respectively.
+Starting with OpenSSL 3.0.0, the function code is always set to zero.
