GetDriveStatus
Routine Description:
Get the drive status.
Arguments:
DriveNumber = The drive to number to use. (1=A,2=B,C=3,...)
PathFormat = Format for the return path.
NW_FORMAT_NETWARE - volume:path
NW_FORMAT_SERVER_VOLUME - server\volume:path
NW_FORMAT_DRIVE - G:\path
NW_FORMAT_UNC - \\server\volume\path
pStatus = A pointer to return the status of the drive.
pConnectionHandle = A pointer to return the connection handle
for the drive.
pRootPath = The pointer to return the base root path. OPTIONAL
pRelativePath = The pointer to return the relative to root path.
pFullPath = The pointer to return the full path.
Return Value:
0x0000 SUCCESSFUL
0x00FF INVALID_DRIVE
