BOOLEAN
VC_ConnectInterrupt(
PDEVICE_INFO pDevInfo,
ULONG Interrupt,
BOOLEAN bLatched
);
The VC_ConnectInterrupt function creates a connection between the specified interrupt number and a kernel-mode video capture driver’s interrupt service routine.
Parameters
pDevInfo
Pointer to the DEVICE_INFO structure returned by VC_Init.
Interrupt
Interrupt number to use.
bLatched
Set to TRUE if the interrupt is latched or FALSE if the interrupt is level-sensitive.
Return Value
Returns TRUE if the operation succeeds. Otherwise returns FALSE.
Comments
The VC_ConnectInterrupt function calls HalGetInterruptVector to obtain a system interrupt vector and IoConnectInterrupt to connect VCKernel.lib’s generic ISR to the interrupt vector. (When an interrupt occurs, VCKernel.lib’s generic ISR calls the driver’s InterruptAcknowledge function.)
Before calling VC_ConnectInterrupt, a kernel-mode driver must call VC_GetResources. It must also call VC_GetCallbackTable and fill in the returned callback table.
