lineSetSendCallerIDState (Windows Embedded CE 6.0)

1/6/2010

Use the lineSetSendCallerIDState function to set Caller ID to send, or to not send, on a mobile-device-originated call. This setting may be overridden on a per-call basis.

Syntax

LONG WINAPI lineSetSendCallerIDState(
  HLINE hLine,
  DWORD dwState
);

Parameters

• hLine
  The line device handle. The line device handle must have been previously obtained by a call to lineOpen with the proper TAPI device ID specified and a device-specific extension version successfully negotiated with lineNegotiateExtVersion.

• dwState
  Points to a DWORD indicating if caller ID information is sent. See the Caller ID State constants for possible values.

Return Value

Returns a positive request identifier if the function is completed asynchronously, or a negative error number if an error occurs. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function succeeds or it is a negative error number if an error occurs. The following are possible return values:

• LINEERR_INVALLINEHANDLE
• LINEERR_NOMEM
• LINEERR_OPERATIONUNAVAIL
• LINEERR_OPERATIONFAILED
• LINEERR_RESOURCEUNAVAIL
• LINEERR_INVALPOINTER
• LINEERR_INVALPARAM
• LINEERR_UNINITIALIZED

Remarks

This is a privileged function.
