lineGetProviderList (Windows Embedded CE 6.0)
1/6/2010
This function returns a list of service providers currently installed in the telephony system.
Syntax
LONG WINAPI lineGetProviderList(
DWORD dwAPIVersion,
LPLINEPROVIDERLIST lpProviderList
);
Parameters
- dwAPIVersion
Highest version of TAPI supported by the application (not necessarily the value negotiated by the lineNegotiateAPIVersion function on some particular line device).
- lpProviderList
Pointer to a memory location where TAPI can return a LINEPROVIDERLIST structure. Prior to calling lineGetProviderList, the application should set the dwTotalSize member of this structure to indicate the amount of memory available to TAPI for returning information.
Return Value
Returns zero if the request succeeds or a negative error number if an error occurs. The following table shows the return values for this function.
| Value | Description |
|---|---|
LINEERR_INCOMPATIBLEAPIVERSION |
The API version is incompatible. |
LINEERR_NOMEM |
Not enough memory is available. |
LINEERR_INIFILECORRUPT |
The INI file is corrupt. |
LINEERR_OPERATIONFAILED |
The operation failed. |
LINEERR_INVALPOINTER |
The pointer is invalid. |
LINEERR_STRUCTURETOOSMALL |
The structure is too small. |
Remarks
Although this is a new function that older applications would not be expected to call, for backward compatibility they should not be prevented from doing so. The function works the same way for all applications.
Note
This function is for TAPI version 2.0 and later.
