Routine Description:
The attributes of a file can be obtained using GetFileAttributes.
This API provides the same functionality as DOS (int 21h, function
43H with AL=0), and provides a subset of OS/2's DosQueryFileInfo.
Arguments:
lpFileName - Supplies the file name of the file whose attributes are to
be set.
Return Value:
Not -1 - Returns the attributes of the specified file. Valid
returned attributes are:
FILE_ATTRIBUTE_NORMAL - The file is a normal file.
FILE_ATTRIBUTE_READONLY - The file is marked read-only.
FILE_ATTRIBUTE_HIDDEN - The file is marked as hidden.
FILE_ATTRIBUTE_SYSTEM - The file is marked as a system file.
FILE_ATTRIBUTE_ARCHIVE - The file is marked for archive.
FILE_ATTRIBUTE_DIRECTORY - The file is marked as a directory.
FILE_ATTRIBUTE_VOLUME_LABEL - The file is marked as a volume lable.
0xffffffff - The operation failed. Extended error status is available
using GetLastError.
