LIBRARY

Standard C Library (libc.a)

SYNOPSIS

#include <sys/types.h>

#include <netinet/in.h>

#include <arpa/nameser.h>

#include <resolv.h>

int dn_skipname (
    u_char ∗comp_domain_name,
    u_char ∗end_of_message );

PARAMETERS

comp_domain_name
Specifies a pointer to a compressed domain name.

end_of_message
Specifies the end of the compressed domain name address.

DESCRIPTION

The dn_skipname() function skips over a compressed domain name. 

The dn_skipname() function is one of a set of subroutines that form the resolver, a set of functions that resolve domain names.  Global information that is used by the resolver functions is kept in the _res data structure.  The include/resolv.h file contains the _res structure definition. 

RETURN VALUES

Upon successful completion, the dn_skipname() function returns the size of the compressed domain name.  If the dn_skipname() function fails, -1 is returned. 

FILES

/etc/resolv.conf
Defines name server and domain name structures, values, and constants.
