NAME

_getlong − Retrieves 32-bit quantities from a byte stream

SYNOPSIS

#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/nameser.h>
#include <resolv.h>
unsigned int _getlong(
        u_char ∗message_ptr );

LIBRARY

Standard C Library (libc)

PARAMETERS

message_ptr
Specifies a pointer into the byte stream.

DESCRIPTION

The _getlong() function gets 32-bit quantities from the byte stream or arbitrary byte boundaries. 

The _getlong() function is one of a set of subroutines that form the resolver, a set of functions that resolves 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 _getlong() function returns an unsigned int (32-bit) value. 

FILES

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