Alters the default attributes of a collection object.

void SetCollectionDefaultAttributes (
    Collection c, 
    SInt32 whichAttributes, 
    SInt32 newAttributes
);

c

A reference to the collection object whose default attributes you want to alter. The behavior of this function is undefined if you do not provide a reference to a valid collection object.

whichAttributes

A mask indicating which bit flags in the c collection’s default attributes you want to alter. For every bit in the whichAttributes parameter, this function takes one of two actions:

• If the bit is set, this function copies the value of the corresponding bit from the newAttributes parameter into the corresponding bit of the default attributes of the c collection.
• If the bit is not set, the corresponding bit of the c collection’s default attributes remains unchanged.

newAttributes

The new values for the bit flags.

DISCUSSION

To examine the attributes of a collection object, use the GetCollectionDefaultAttributes function.

To change the attributes of a specific item in a collection, use the functions SetCollectionItemInfo and SetIndexedCollectionItemInfo.
