HSetFInfo changes Finder-specific information about a file. This includes

the file's type, the signature of its creator, Finder flags (such as whether the

icon is displayed), and the display position of the file's icon within its window.

vRefNum is the reference number of the volume or working directory

containing the file or directory fileName. 0 indicates the default

dirID is the ID of the directory that contains the file to set info about

fileName is the address of a length-prefixed, pascal-style string containing

the name of the target file. It may be a partial or full pathname,

fndrInfo is the address of a 16-byte FInfo structure containing the desired

values of Finder specific information to be changed. Normal usage is

to pre-set all fields with current values by first calling GetFInfo,

Notes: The FInfo structure maintains the primary information used by the Finder

in locating the icon to display, where to display it, and which application to

run when its icon is double-clicked. It is the same information as in the

ioFlFndrInfo field of the FileParam structure, which is passed to the

custom "file filters" used in the Standard File Package (see SFGetFile).

Additional Finder information is maintained in an FXInfo structure, which

can be obtained via PBGetCatInfo. In all operations where you modify

file-de scriptive information, the normal usage is to obtain a copy of the

current information before modifying selected fields and updating the disk.
