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.
