RasGetCountryInfo info  Overview  Group

The RasGetCountryInfo function retrieves country-specific dialing information from the Windows Telephony list of countries.

For more information about country-specific dialing information and TAPI country identifiers, see the Win32 Telephony (TAPI) Programmer’s Reference.

DWORD RasGetCountryInfo(

Parameters

lpRasCtryInfo

Pointer to a RASCTRYINFO structure that receives the country-specific dialing information followed by additional bytes for a country description string. Before calling the function, set the dwSize member of the structure to sizeof(RASCTRYINFO) to identify the version of the structure. You must also set the dwCountryId member to the TAPI country identifier of the country for which to get information.

The size of the buffer should be at least 256 bytes.

lpdwSize

Pointer to a variable that contains the size, in bytes, of the buffer pointed to by the lpRasCtryInfo parameter. On return, the function sets this variable to the number of bytes required.

Return Values

If the function succeeds, the return value is zero.

If the function fails, the return value can be one of the following error codes.

Remarks

To enumerate information for all countries in the Windows Telephony list, set the dwCountryId member of the RASCTRYINFO structure to 1 in the initial RasGetCountryInfo call. This causes the function to return information for the first country in the list. The value returned in the dwNextCountryId member is the country identifier of the next country in the list. Use this value in repeated calls to RasGetCountryInfo until dwNextCountryID returns zero, indicating the last country in the list.
