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.
