Detach a driver from a PCI device
#include <hw/pci.h> int pci_detach_device( void* handle );
- The handle returned by pci_attach_device().
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pci_detach_device() function detaches a driver from a PCI device. Any resources allocated with pci_attach_device() are released, unless you attached the device with the PCI_PERSIST flag set.
|You must successfully call pci_attach() before calling any of the other PCI functions.|
- No device could be found for handle.
- You haven't called pci_attach(), or the call to it failed.
