2/*
3 *@@sourcefile prfh2.c:
4 * contains more Presentation Manager helper functions
5 * which deal with Profile (Prf*) functions.
6 *
7 * This file is new with V0.9.4 (2000-07-26) [umoeller].
8 *
9 * As opposed to the functions in prfh.c, these require
10 * linking against other helpers. As a result, these have
11 * been separated from prfh.c to allow linking against
12 * prfh.obj only.
13 *
14 * Function prefixes:
15 * -- prfh* Prf (profile, INI) helper functions
16 *
17 * Note: Version numbering in this file relates to XWorkplace version
18 * numbering.
19 *
20 *@@header "helpers\prfh.h"
21 *@@added V0.9.4 (2000-07-27) [umoeller]
