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.
