control

A value of type

-
propertyCreator
-
A four-character code. Pass your program's signature, as registered through Apple Developer Technical Support. If your program is of a type that would not normally have a signature (for example, a plug-in), you should still register and use a signature in this case, even though your program's file may not have the same creator code as the signature that you register. The
'macs'
property signature is reserved for the system and should not be used.
-
propertyTag
-
A four-character code. Pass a value identifying the data. You define the tag your application uses to identify the data.

An unsigned 32-bit integer. Pass a value specifying the size of the data.

A pointer to data of any type. Pass a pointer to a buffer containing the data to be associated; this buffer should be at least as large as the value specified in the
propertySize
parameter.
-
function result
-
A result code. See
Result Codes for the Mac OS 8.5 Control Manager
