lineGetCountryW function (tapi.h)
The lineGetCountry function fetches the stored dialing rules and other information related to a specified country/region, the first country/region in the country/region list, or all countries/regions.
LONG lineGetCountryW(
DWORD dwCountryID,
DWORD dwAPIVersion,
LPLINECOUNTRYLIST lpLineCountryList
);
dwCountryID
Country/region identifier (not the country code) of the country/region for which information is to be obtained. If the value 1 is specified, information on the first country/region in the country/region list is obtained. If the value 0 is specified, information on all countries/regions is obtained (which can require a great deal of memory — 20 KB or more).
dwAPIVersion
Highest version of TAPI supported by the application (not necessarily the value negotiated by lineNegotiateAPIVersion on some particular line device).
lpLineCountryList
Pointer to a location to which a LINECOUNTRYLIST structure is loaded. Prior to calling lineGetCountry, the application must set the dwTotalSize member of this structure to indicate the amount of memory available to TAPI for returning information.
Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:
LINEERR_INCOMPATIBLEAPIVERSION, LINEERR_NOMEM, LINEERR_INIFILECORRUPT, LINEERR_OPERATIONFAILED, LINEERR_INVALCOUNTRYCODE, LINEERR_STRUCTURETOOSMALL, LINEERR_INVALPOINTER.
Poznámka
The tapi.h header defines lineGetCountry as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
