Last change on this file since 1594 was 1551, checked in by Gregg Young, 15 years ago

This code adds the semaphores to prevent a rescan from starting before the current one is finished; it fixes the double directory listing in the tree container and streamlines scanning. It update mapsym.pl to the latest version. Some code cleanup is included

11 24 May 05 SHL Rework Win_Error usage
12 25 May 05 SHL Rework for ProcessDirectory
13 28 May 05 SHL Clean while reading code
14 24 Oct 05 SHL Delete obsolete code
15 22 Jul 06 SHL Check more run time errors
16 19 Oct 06 SHL Stubby - correct . and .. detect
17 22 Mar 07 GKY Use QWL_USER
18 01 Aug 07 SHL Sync with CNRITEM mods
19 06 Aug 07 GKY Reduce DosSleep times (ticket 148)
20 20 Aug 07 GKY Move #pragma alloc_text to end for OpenWatcom compat
21 29 Feb 08 GKY Use xfree where appropriate
22 24 Nov 08 GKY remove redundant code and minor speed up of Stubby
23 25 Dec 08 GKY Add ProcessDirectoryThread to allow optional recursive drive scan at startup.
24 25 Dec 08 GKY Add DRIVE_RSCANNED flag to monitor for the first recursive drive scan per session
25 to prevent duplicate directory names in tree following a copy before initial scan.
26 08 Mar 09 GKY Additional strings move to PCSZs in init.c
27 13 Dec 09 GKY Fixed separate paramenters. Please note that appname should be used in
28 profile calls for user settings that work and are setable in more than one
29 miniapp; FM3Str should be used for setting only relavent to FM/2 or that
30 aren't user settable; realappname should be used for setting applicable to
31 one or more miniapp but not to FM/2
32 17 JAN 10 GKY Changes to get working with Watcom 1.9 Beta (1/16/10). Mostly cast CHAR CONSTANT * as CHAR *.
