source: trunk/dll/pathutil.c@ 1398

Last change on this file since 1398 was 1398, checked in by Gregg Young, 17 years ago

Move embeded strings to PCSZ variables or string table; Eliminate Error2 functions Runtime_Error with NULL format string returns "No data" error. Change declares from PSZ to PCSZ in functions where the variable isn't changed. Added btm as an executable file type in several additional places. Use fProtectOnly to prevent attempt to execute Dos and Win programs on "Protect only" installs in several additional places.

11 05 Jan 08 SHL Move from arccnrs.c and comp.c to here
[920]12 06 Jan 08 GKY Add NormalizeCmdLine to check program strings on entry
[985]13 29 Feb 08 GKY Changes to enable user settable command line length
[1247]14 15 Oct 08 GKY Fix NormalizeCmdLine to check all 5 executible extensions when no extension provided;
[1394]15 use searchapath to check for existance of file types not checked by DosQAppType;
