GetMenuItemPropertySize

Obtains the size of a piece of data that has been previously associated with a menu item.



 
pascal OSStatus GetMenuItemPropertySize (

                     MenuHandle menu,

                     UInt16 item,

                     OSType propertyCreator,

                     OSType propertyTag,

                     UInt32 *size);

menu: A value of type MenuHandle . Pass a handle to the menu containing the item to be examined for associated data.
item: An unsigned 16-bit integer. Pass a value specifying the item number of the menu item or 0 if the data is associated with the menu as a whole.
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 the application-defined code identifying the data.
size: A pointer to an unsigned 32-bit integer. On return, this value is set to the actual size of the data.
function result: A result code. See Result Codes for the Mac OS 8.5 Menu Manager .

DISCUSSION

If you want to retrieve a piece of associated data with the function GetMenuItemProperty , you will typically need to use the GetMenuItemPropertySize function beforehand to determine the size of the associated data.
