ERR_get_error(3)		    OpenSSL		      ERR_get_error(3)

NAME
       ERR_get_error, ERR_peek_error, ERR_get_error_line, ERR_peek_error_line,
       ERR_get_error_line_data, ERR_peek_error_line_data - obtain error code
       and data

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);
	unsigned long ERR_peek_error_line_data(const char **file, int *line,
		const char **data, int *flags);

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 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() 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 *file and *line, unless these are NULL.

       ERR_get_error_line_data() and ERR_peek_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. If it has been allocated by OPENSSL_malloc(),
       *flags&ERR_TXT_MALLOCED is true.

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.
