Description
Sets the end of the file marker to truncate the resource at the indicated position.
Call SetSize to set the size of the resource. SetSize calls Seek to go to the indicated position, and then writes an end of file marker. If the size of the resource cannot be changed, an exception is raised. For example, calling SetSize for a file handle that was opened in fmOpenRead mode will raise an exception.
