ulInfoLevel (ULONG) - input

The level of file information required.

Possible values are:

• FIL_STANDARD Level 1 file information (return standard file information).

• FIL_QUERYEASIZE Level 2 file information (return full EA size).

• FIL_QUERYEASFROMLIST Level 3 file information (return requested EA).

  The structures described in pfindbuf indicate the information returned for each of these levels.

  Regardless of the level specified, a DosFindFirst request (and an associated DosFindNext) request on a handle returned by DosFindFirst) always includes Level 1 information as part of the information that is returned; however, when Level 1 information is specifically requested, and flAttribute specifies hidden files, system files, or subdirectory files, an inclusive search is made. That is, all normal file entries plus all entries matching any specified attributes are returned. Normal files are files without any mode bits set. They may be read from or written to.
