VoidPtr is generic (void *), and FieldPtr (FieldType *) points to a
FieldType struct. This matters for C++, so I type cast something like
GetObject to a pointer of the type of object I'm interested in -
FieldType*, ControlType*, whatever.

Subject: VoidPtr and FieldPtr Confusion
Hi
I am working through
Palm OS Programming from the Ground Up
and have run into a confusing situation.
In one example there is a function
static void setText(FieldPtr, CharPtr);
In the call for this function the FieldPtr parameter is supplied as
follows...
setText(getObject(form, ContactDetailFirstNameField), precord +
DB_FIRST_NAME_START);
in this setText call...
getObject returns a VoidPtr
Is a VoidPtr and a FieldPtr the same thing?
Thanks in advance
