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);
DESCRIPTIONERR_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.
SEE ALSOerr(3), ERR_error_string(3), ERR_GET_LIB(3)HISTORYERR_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.
