-=head1 SYNOPSIS
-
- #include <openssl/err.h>
-
- unsigned long ERR_get_error(void);
- unsigned long ERR_peek_error(void);
- unsigned long ERR_peek_last_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_peek_last_error_line(const char **file, int *line);
-
- unsigned long ERR_get_error_line_data(const char **file, int *line,
- const char **data, int *flags);
- unsigned long ERR_peek_error_line_data(const char **file, int *line,
- const char **data, int *flags);
- unsigned long ERR_peek_last_error_line_data(const char **file, int *line,
- const char **data, int *flags);

-=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 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(), 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.
