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);
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 ERR_GET_LIB(3) for obtaining information about location
and reason of the error, and 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 *file and *line, unless these are
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 *data and *flags,
unless these are NULL. *data contains a string if
*flags&ERR_TXT_STRING is true.

An application MUST NOT free the *data pointer (or any other
pointers returned by these functions) with OPENSSL_free() as
freeing is handled automatically by the error library.
RETURN VALUES
The error code, or 0 if there is no error in the queue.

HISTORY
ERR_get_error(), ERR_peek_error(), ERR_get_error_line() and
ERR_peek_error_line() are available in all versions of
SSLeay and OpenSSL. ERR_get_error_line_data() and
ERR_peek_error_line_data() were added in SSLeay 0.9.0.
ERR_peek_last_error(), ERR_peek_last_error_line() and
ERR_peek_last_error_line_data() were added in OpenSSL 0.9.7.
