lineGetProviderList

  • Article

This function returns a list of service providers currently installed in the telephony system.

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 Values

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.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Tapi.h.
