Use the lineSetGPRSClass function to set the General Packet Radio Service (GPRS) class of the device.


LONG WINAPI lineSetGPRSClass(
  HLINE hLine,
  DWORD dwClass
);

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.

dwClass

The line GPRS class. See the GPRS Classes constants for possible values.

Returns a positive request identifier if the function completes 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_RESOURCEUNAVAIL
  • LINEERR_INVALLINEHANDLE
  • LINEERR_STRUCTURETOOSMALL
  • LINEERR_INVALPOINTER
  • LINEERR_UNINITIALIZED
  • LINEERR_NOMEM
  • LINEERR_OPERATIONUNAVAIL
  • LINEERR_OPERATIONFAILED

This is a privileged function.

Not implemented for CDMA.
