NAME
ipq_errstr, ipq_perror --- libipq error handling routines
SYNOPSIS
#include <linux/netfilter.h>
#include <libipq.h>
char *ipq_errstr(void);
void ipq_perror(const char *s);
DESCRIPTION
The
ipq_errstr
function returns a descriptive error message based on the current
value of the internal
ipq_errno
variable. All libipq API functions set this internal variable
upon failure.
The
ipq_perror
function prints an error message to stderr corresponding to the
current value of the internal
ipq_error
variable, and the global
errno
variable (if set). The error message is prefixed with the string
s
as supplied by the application. If
s
is NULL, the error message is prefixed with the string "ERROR".
RETURN VALUE
ipq_errstr
returns an error message as outlined above.
BUGS
None known.
