Retrieves short byte quantities.
Standard C Library (libc.a)
unsigned short getshort ( MessagePtr)
The _getshort subroutine gets quantities from the byte stream or arbitrary byte boundaries.
The _getshort subroutine is one of a set of subroutines that form the resolver, a set of functions that resolve domain names. Global information used by the resolver subroutines is kept in the _res data structure. The /usr/include/resolv.h file contains the _res structure definition.
|MessagePtr||Specifies a pointer into the byte stream.|
The _getshort subroutine returns an unsigned short (16-bit) value.
The _getshort subroutine is part of Base Operating System (BOS) Runtime.
All applications containing the _getshort subroutine must be compiled with _BSD set to a specific value. Acceptable values are 43 and 44. In addition, all socket applications must include the BSD libbsd.a library.
|Defines name server and domain names.|
The dn_comp subroutine, dn_expand subroutine, _getlong subroutine, putlong subroutine, putshort subroutine, res_init subroutine, res_mkquery subroutine, res_send subroutine.
