NAME

	ParentChunk -- get the nesting context node for the given chunk. (V36)

SYNOPSIS

	parent = ParentChunk(contextNode);
D0 A0
struct ContextNode *ParentChunk(struct ContextNode *);

FUNCTION

	Returns a context node for the chunk containing the chunk for the
given context node. This function effectively moves down the context
stack into previously pushed contexts. For example, to get a
ContextNode pointer for the enclosing FORM chunk while reading a data
chunk, use: ParentChunk(CurrentChunk(iff)) to find this pointer.
The ContextNode structure contains information on the type of chunk
and its size.

INPUTS

	contextNode - pointer to a context node.

RESULT

	parent - pointer to the enclosing context node or NULL if none.
