/* SYNOPSIS */
|
|
AROS_LHA(LONG, unitNumber, D0),
|
|
|
|
/* LOCATION */
|

struct Library *, IFFParseBase, 41, IFFParse)
|
|
|
|
/* FUNCTION
|
|
Opens the clipboard.device with the specified unit.
|
|
Allocates and initializes a ClipboardHandle struct which should
|
|
be put into the iff_Stream field of the IFFHandle when the
|
|
handle is initialized with InitIFFasClip().
|
|
|
|
|
|
INPUTS
|
|
unitNumber - a clipboard device unit number (usually PRIMARY_CLIP).
|
|
|
|
RESULT
|
|
ch - pointer to ClipboardHandle struct or NULL if unsuccessful.
