WCMP_PROVIDER_SPECIFIC_DATA (Windows Embedded CE 6.0)

  • Статья

1/6/2010

This structure is used for provider-specific data for use with SmsSendMessage and SmsReadMessage calls. Supporting Global System for Mobile Communications (GSM) Wireless Control Message Protocol (WCMP) is required for compliance as an Short Message Service (SMS) bearer.

Syntax

typedef struct wcmp_provider_specific_data_tag {
    WCMP_PROVIDER_SPECIFIC_MESSAGE_TYPE wcmppsMessageType;
    WORD wParam1;
    WORD wParam2;
    WORD wParam3;
    SMS_ADDRESS smsaAddress;
} WCMP_PROVIDER_SPECIFIC_DATA;

Members

  • wcmppsMessageType
    The type of WCMP message.

  • wParam1, wParam2, wParam3, smsaAddress
    Use of these parameters is shown in the following table. The WCMP type and code are shown for reference only.

Remarks

The WDP layer sends the WCMP_MESSAGETOOBIG message if an incoming primitive exceeds its limit. However, the WDP Short Message Service (SMS) provider will also issue this WCMP message directly if a multipart message is bigger than the provider can handle.

Also note that the WDP layer, not the GSM WCMP provider, sends replies to WCMP_ECHOREQUEST messages.
