This GetPathCase function does resolve the path with wildcard pattern, and fix the alphabet cases, by using kernel32!FindFirstFile function. Enable wildcard at the middle of the file path in cmd.exe by fixing this function. JIRA issue: CORE-6609 JIRA issue: CORE-13906 - Fix GetPathCase function for supporting wildcard at the - middle of the file path. - Make GetPathCase string-safe. - Optimize GetPathCase.

* History:
|
|
*
|
|
* 07/12/98 (Rob Lake)
|
|
* started
|
|
*
|
|
* 07/13/98 (Rob Lake)
|
|
* moved functions in here
|
|
*
|
|
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* added config.h include
|
|
*
|
|
* 18-Dec-1998 (Eric Kohl)
|
|
* Changed split() to accept quoted arguments.
|
|
* Removed parse_firstarg().
|
|
*
|
|
* 23-Jan-1999 (Eric Kohl)
|
|
* Fixed an ugly bug in split(). In rare cases (last character
|
|
* of the string is a space) it ignored the NULL character and
|
|
* tried to add the following to the argument list.
|
|
*
|
|
* 28-Jan-1999 (Eric Kohl)
|
|
* FileGetString() seems to be working now.
|
|
*
|
|
* 06-Nov-1999 (Eric Kohl)
|
|
* Added PagePrompt() and FilePrompt().
|
|
*
|
|
* 30-Apr-2005 (Magnus Olsen <magnus@greatlord.com>)
|
|
* Remove all hardcoded strings in En.rc
