This structure is used for provider-specific data for use with the functions SmsSendMessageand SmsReadMessage. The Wireless Datagram Protocol (WDP) provider is a generic protocol that allows WDP applications to pass data through the Short Message Service (SMS) bearer.

WDP is the bottom layer of the Wireless Application Protocol (WAP) stack. It provides a consistent connection to higher layers in the protocol stack by abstracting the underlying bearers. Note that the WDP provider described in this document is simply the bearer protocol used for supporting WDP over SMS, it is not the actual WDP interface. See the WAP-200-WDP "Wireless Datagram Protocol (WDP)" specification for more detail.

The following structure provides a description of the fields encoded in the provider-specific portion of this message. The source and destination port model is analogous to the port model used in the sockets architecture.

Syntax 

typedef struct wdp_provider_specific_data_tag {
	WDP_PROVIDER_SPECIFIC_PORT_ADDRESSING
