Go to RapidDriver Main Page

Reads the hardware configuration (resources) of the PCI device.

Language

Description

C/C++
void GetHardwareConfuguration ( HANDLE hPci, HW_DEV_CONFIG * Cfg);
Delphi
procedure GetHardwareConfuguration ( hPci: THandle, var Cfg: HW_DEV_CONFIG); stdcall
VB
Sub GetHardwareConfuguration ( ByVal hPci As Long, ByRef Cfg As HW_DEV_CONFIG)


Parameters:
hPci - the handle returned by a successful call to OpenRapidPci  
Cfg - hardware resources of the PCI device  
 
Return Value :
None

Comments:
The hardware configuration is not the same as PCI header.
