IPQ_ERRSTR(3) Linux Programmer's Manual IPQ_ERRSTR(3) 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. AUTHOR
