mplist_put - Set the value of a property in a property list.
, void * val
Set the value of a property in a property list.
The mplist_put() function searches property list plist from the beginning for a
property whose key is key .
If such a property is found, its value is
changed to value .
Otherwise, a new property whose key is key and value
is value is appended at the end of plist .
See the documentation of
mplist_add() for the restriction on key and val .
If key is a managing key, val must be a managed object. In this case, the
reference count of the old value, if not NULL ,
is decremented by one,
and that of val is incremented by one.
If the operation was successful, mplist_put() returns a
sublist of plist whose first element is the just modified or added one.
Otherwise, it returns NULL .
