lineGetCountry
The lineGetCountry function fetches the stored dialing rules and other information related to a
specified country, the first country in the country list, or all countries.
LONG lineGetCountry(
DWORD dwCountryID,
|
| DWORD dwAPIVersion,
|
| LPLINECOUNTRYLIST lpLineCountryList
|
| );
|
|
Parameters
dwCountryID
The country ID (not the country code) of the country for which information is to be obtained. If
the value 1 is specified, information on the first country in the country list
is obtained. If the value 0 is specified, information on all countries is
obtained (which may require a great deal of memory 20Kbytes or more).
dwAPIVersion
The highest version of TAPI supported by the application (not necessarily the value negotiated by lineNegotiateAPIVersion on some particular line device).
lpLineCountryList
A pointer to a location to which a LINECOUNTRYLIST structure will be loaded. Prior to calling lineGetCountry, the application should set the dwTotalSize field of this structure to indicate the amount of memory available to TAPI
for returning information.
Return Values
Returns zero if the request is successful or a negative error number if an
error has occurred. Possible return values are:
LINEERR_INCOMPATIBLEAPIVERSION, LINEERR_NOMEM, LINEERR_INIFILECORRUPT,
LINEERR_OPERATIONFAILED, LINEERR_INVALCOUNTRYCODE, LINEERR_STRUCTURETOOSMALL,
LINEERR_INVALPOINTER.
Remarks
Although this is a new function which older applications would not be expected
to call, for backward compatibility, they should not be prevented from doing
so. The function will work the same way for all applications.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
