README file for directory ./include of the NTP Version 3 distribution This directory contains the include files used by most programs in this distribution. The ./sys directory in this directory contains system header files used by the clock discipline and STREAMS modules in the ../kernel directory. Note that multicast support (MCAST define) requires the header file /usr/include/netinet/in.h for the particular architecture to be in place. This file is constructed during the installation process in older systems; it is already in place for those machines that support multicast ex box. The file in.h included in this distribution is for Suns; the files for other systems can be found in the multicast distribtutions for each architecture separately. If the precision-time kernel (KERNEL_PLL define) is configured, the installation process requires the header file /usr/include/sys/timex.h for the particular architecture to be in place. The file timex.h included in this distribution is for Suns; the files for other systems can be found in the kernel distributions available from the manufacturer's representatives.
