CMsvMimeHeaders Class Reference

class CMsvMimeHeaders : public CBase

Utility class to represent commonly used Mime Headers. This object represents a number of common Mime Headers into a single class. It is intended that this class is used to represent the Mime Headers for an attachment represented by the CMsvAttachment class when using the Attachment API. The Mime header data can be associated with an attachment and stored and restored using the StoreL and RestoreL methods.
