DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

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