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.
