=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/err.h>
|
||
|
|
|
||
|
|
unsigned long ERR_get_error(void);
|
||
|
|
unsigned long ERR_peek_error(void);
|
||
|
|
|
||
|
|
unsigned long ERR_get_error_line(const char **file, int *line);
|
||
|
|
unsigned long ERR_peek_error_line(const char **file, int *line);
|
||
|
|
|
||
|
|
unsigned long ERR_get_error_line_data(const char **file, int *line,
|
||
|
|
const char **data, int *flags);
|

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
ERR_get_error() returns the last 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 last error code from the thread's
|
||
|
|
error queue without modifying it.
|
||
|
|
|
||
|
|
See L<ERR_GET_LIB(3)|ERR_GET_LIB(3)> for obtaining information about
|
||
|
|
location and reason of the error, and
|
||
|
|
L<ERR_error_string(3)|ERR_error_string(3)> for human-readable error
|
||
|
|
messages.
|
||
|
|
|
||
|
|
ERR_get_error_line() and ERR_peek_error_line() are the same as the
|
||
|
|
above, but they additionally store the file name and line number where
|
||
|
|
the error occurred in *B<file> and *B<line>, unless these are B<NULL>.
|
||
|
|
|
||
|
|
ERR_get_error_line_data() and ERR_peek_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>. If it has been allocated by Malloc(),
|
||
|
|
*B<flags>&B<ERR_TXT_MALLOCED> is true.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
The error code, or 0 if there is no error in the queue.
