NAME

_getshort − Retrieves short quantities from a byte stream

LIBRARY

Standard C Library (libc.so, libc.a)

SYNOPSIS

#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/nameser.h>
#include <resolv.h>

unsigned short _getshort (
        u_char ∗message_ptr );

PARAMETERS

message_ptrSpecifies a pointer into the byte stream. 

DESCRIPTION

The _getshort() function gets 16-bit quantities from the byte stream or arbitrary byte boundaries. 

The _getshort() 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 data structure definition. 

RETURN VALUES

Upon successful completion, the _getshort() function returns an unsigned short (16-bit) value. 

FILES

/etc/resolv.conf
Defines name server and domain names.
