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.
