astClear

Clear attribute values for an Object

Description:

This function clears the values of a specified set of attributes for an Object. Clearing an attribute cancels any value that has previously been explicitly set for it, so that the standard default attribute value will subsequently be used instead. This also causes the astTest function to return the value zero for the attribute, indicating that no value has been set.

Parameters:

this
Pointer to the Object.
attrib
Pointer to a null-terminated character string containing a comma-separated list of the names of the attributes to be cleared.
