Members

get_HasCurrentHeader

True when the iterator hasn't run out of headers.

public HRESULT get_HasCurrentHeader(BOOL * hasCurrent)

If the collection over which the iterator is iterating is empty or if the iterator has gone past the end of the collection then this is false.

GetCurrentHeader

Get the name and value of the current HTTP header of the iterator.

public HRESULT GetCurrentHeader(LPWSTR * name, LPWSTR * value)

This method will fail if the last call to MoveNext set hasNext to FALSE.

MoveNext

Move the iterator to the next HTTP header in the collection.

public HRESULT MoveNext(BOOL * hasNext)

The hasNext parameter will be set to FALSE if there are no more HTTP headers. After this occurs the GetCurrentHeader method will fail if called.
