/* RCS $Id: sysintf.c,v 1.11 2007-09-20 14:34:06 vg Exp $ -- -- SYNOPSIS -- System independent interface -- -- DESCRIPTION -- These are the routines constituting the system interface. -- The system is taken to be essentially POSIX conformant. -- The original code was extensively revised by T J Thompson at MKS, -- and the library cacheing was added by Eric Gisin at MKS. I then -- revised the code yet again, to improve the lib cacheing, and to -- make it more portable. -- -- The following is a list of routines that are required by this file -- in order to work. These routines are provided as functions by the -- standard C lib of the target system or as #defines in system/sysintf.h -- or via appropriate C code in the system/ directory for the given -- system. -- -- The first group must be provided by a file in the system/ directory -- the second group is ideally provided by the C lib. However, there -- are instances where the C lib implementation of the specified routine -- does not exist, or is incorrect. In these instances the routine -- must be provided by the the user in the system/ directory of dmake. -- (For example, the bsd/ dir contains code for putenv(), and tempnam()) -- -- DMAKE SPECIFIC: -- seek_arch() -- touch_arch() -- void_lcache() -- runargv() -- DMSTAT() -- Remove_prq() -- -- C-LIB SPECIFIC: (should be present in your C-lib) -- utime() -- time() -- getenv() -- putenv() -- getcwd() -- signal() -- chdir() -- tempnam() -- -- AUTHOR -- Dennis Vadura, dvadura@dmake.wticorp.com -- -- WWW -- http://dmake.wticorp.com/ -- -- COPYRIGHT -- Copyright (c) 1996,1997 by WTI Corp.
