Routine Description:
|
|
|
|
This function takes a path and returns an array of snapshot-paths to the file.
|
|
(These are the paths to be passed to Win32 functions to obtain handles to the
|
|
previous versions of the file.)
|
|
|
|
Arguments:
|
|
|
|
lpszFilePath - The UNICODE path to the file or directory
|
|
dwQueryFlags - See Notes below
|
|
ppszPathMultiSZ - Upon successful return, the allocated array of the path
|
|
iNumberOfPaths - Upon successful return, the number of paths returned
|
|
|
|
|
|
Return Value:
|
|
|
|
Windows Error code
|
|
|
|
Notes:
|
|
|
|
- The user is responsible for freeing the returned buffer with LocalFree
|
|
- The possible flags are:
|
|
|
|
Return only the path names where the file exists
|
|
#define QUERY_SNAPSHOT_EXISTING 0x1
|
|
|
|
Return the minimum set of paths to the different versions of the
|
|
files. (Does LastModifiedTime checking)
