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.
