NAME
mplist_put - Set the value of a property in a property list.SYNOPSIS
MPlist* mplist_put (MPlist * plist, MSymbol key, void * val)DESCRIPTION
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.
RETURN VALUE
- 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.
