3 *@@sourcefile procstat.c:
4 * functions for querying process information.
5 * This is an easy-to-use interface to the
6 * messy 16-bit DosQProcStatus function.
7 *
8 * Usage: All OS/2 programs.
9 *
10 * Function prefixes (new with V0.81):
11 * -- prc* Query Process helper functions
12 *
13 * Based on Kai Uwe Rommel's "dosqproc" package
14 * available at Hobbes:
15 * Kai Uwe Rommel - Wed 25-Mar-1992
16 * Sat 13-Aug-1994
17 *
18 * Note: If you link against procstat.obj, you
19 * need to import the following in your .DEF file:
20 *
21 + IMPORTS
22 + DOSQPROCSTATUS = DOSCALLS.154
23 + DosQuerySysState = DOSCALLS.368
24 *
25 * or linking will fail.
26 *
27 * Note: Version numbering in this file relates to XWorkplace version
28 * numbering.
