=head1 DESCRIPTION
|
||
|
|
|
||
|
|
ERR_get_error() returns the earliest error code from the thread's error
|
||
|
|
queue and removes the entry. This function can be called repeatedly
|
||
|
|
until there are no more error codes to return.
|
||
|
|
|
||
|
|
ERR_peek_error() returns the earliest error code from the thread's
|
||
|
|
error queue without modifying it.
|
||
|
|
|
||
|
|
ERR_peek_last_error() returns the latest error code from the thread's
|
||
|
|
error queue without modifying it.
|
||
|
|
|
||
|
|
See L<ERR_GET_LIB(3)> for obtaining information about
|
||
|
|
location and reason of the error, and
|
||
|
|
L<ERR_error_string(3)> for human-readable error
|
||
|
|
messages.
|
||
|
|
|
||
|
|
ERR_get_error_line(), ERR_peek_error_line() and
|
||
|
|
ERR_peek_last_error_line() are the same as the above, but they
|
||
|
|
additionally store the filename and line number where
|
||
|
|
the error occurred in *B<file> and *B<line>, unless these are B<NULL>.
|
||
|
|
|
||
|
|
ERR_get_error_line_data(), ERR_peek_error_line_data() and
|
||
|
|
ERR_peek_last_error_line_data() store additional data and flags
|
||
|
|
associated with the error code in *B<data>
|
||
|
|
and *B<flags>, unless these are B<NULL>. *B<data> contains a string
|
||
|
|
if *B<flags>&B<ERR_TXT_STRING> is true.
|
||
|
|
|
||
|
|
An application B<MUST NOT> free the *B<data> pointer (or any other pointers
|
||
|
|
returned by these functions) with OPENSSL_free() as freeing is handled
|
||
|
|
automatically by the error library.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
The error code, or 0 if there is no error in the queue.
