=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 further specific information
|
|
such as the 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 ERR_get_error(),
|
|
ERR_peek_error() and ERR_peek_last_error(), but on success they
|
|
additionally store the filename and line number where
|
|
the error occurred in *B<file> and *B<line>, as far as they are not B<NULL>.
|
|
An unset filename is indicated as B<"">, i.e., an empty string.
|
|
An unset line number is indicated as B<0>.
|
|
|
|
A pointer returned this way by these functions and the ones below
|
|
is valid until the respective entry is removed from the error queue.
|
|
|
|
ERR_get_error_func(), ERR_peek_error_func() and
|
|
ERR_peek_last_error_func() are the same as ERR_get_error(),
|
|
ERR_peek_error() and ERR_peek_last_error(), but on success they
|
|
additionally store the name of the function where the error occurred
|
|
in *B<func>, unless it is B<NULL>.
|
|
An unset function name is indicated as B<"">.
|
|
|
|
ERR_get_error_data(), ERR_peek_error_data() and
|
|
ERR_peek_last_error_data() are the same as ERR_get_error(),
|
|
ERR_peek_error() and ERR_peek_last_error(), but on success they
|
|
additionally store additional data and flags associated with the error
|
|
code in *B<data> and *B<flags>, as far as they are not B<NULL>.
|
|
Unset data is indicated as B<"">.
|
|
In this case the value given for the flag is irrelevant (and equals B<0>).
|
|
*B<data> contains a string if *B<flags>&B<ERR_TXT_STRING> is true.
|
|
|
|
ERR_get_error_all(), ERR_peek_error_all() and
|
|
ERR_peek_last_error_all() are combinations of all of the above.
|
|
|
|
ERR_get_error_line_data(), ERR_peek_error_line_data() and
|
|
ERR_peek_last_error_line_data() are older variants of ERR_get_error_all(),
|
|
ERR_peek_error_all() and ERR_peek_last_error_all(), and should no longer
|
|
be used.
|
|
|
|
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.

=head1 HISTORY
|
|
|
|
ERR_get_error_func(), ERR_peek_error_func(), ERR_peek_last_error_func(),
|
|
ERR_get_error_data(), ERR_peek_error_data(), ERR_peek_last_error_data(),
|
|
ERR_get_error_all(), ERR_peek_error_all() and ERR_peek_last_error_all()
|
|
were added in OpenSSL 3.0.
|
|
|
|
ERR_get_error_line_data(), ERR_peek_error_line_data() and
|
|
ERR_peek_last_error_line_data() became deprecated in OpenSSL 3.0.
