FPGA_CONTROL_LINK callback function (wdm.h)

  • Article

Reserved for future use.

Enables or disables the link between the given FPGA device and its parent bridge.

Syntax

FPGA_CONTROL_LINK FpgaControlLink;

NTSTATUS FpgaControlLink(
  [_In_reads_opt_(_Inexpressible_("varies"))] PVOID Context,
  [_In_]                                      BOOLEAN Enable
)
{...}

Parameters

Context

The handle to the bus extension.

[_In_] Enable

A boolean value that indicates whether the link should be enabled or disabled. TRUE indicates enabled; FALSE otherwise.

Return value

Return STATUS_SUCCESS if the operation succeeds. Otherwise, return an appropriate NTSTATUS Values error code. For more information, see NTSTATUS Values.

Remarks

A device driver that successfully queries for the GUID_PCI_FPGA_CONTROL_INTERFACE interface receives a pointer to a FPGA_CONTROL_INTERFACE structure in which the driver sets the ControlLink member to a pointer to its implementation of the FPGA_CONTROL_CONFIG_SPACE callback function.
