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.
