GetDiskObject

Read in a Workbench disk object from disk.

Declaration

Source position: icon.pas line 234

function GetDiskObject(

  const Name: PChar

):PDiskObject;

Arguments

Name

  

Name of the object or nil if you just want a DiskObject structure allocated for you (useful when calling AddAppIcon() in workbench.library).

Function result

The Workbench disk object in question

Description

This routine reads in a Workbench disk object in from disk. The name parameter will have ".info" postpended to it, and the icon file of that name will be read. If the call fails, it will return nil. The reason for the failure may be obtained via IoErr().

Using this routine protects you from any future changes to the way icons are stored within the system.

A TFreeList structure is allocated just after the DiskObject structure; FreeDiskObject() makes use of this to get rid of the memory that was allocated.
