Syntax

int MVIbp_SetModuleInterrupt(MVIHANDLE handle);

Parameters

handle

Handle returned by previous call to MVIbp_Open

Description

MVIbp_SetModuleInterrupt generates a Module Interrupt to the host Controller.

This function can only be used when the module is configured as a Class 4

module.

handle must be a valid handle returned from MVIbp_Open.

This function waits for the host Controller to acknowledge the interrupt, which

may take up to 2.5 seconds. The host Controller must be in RUN mode and must

contain a Module Interrupt function routine to process and acknowledge the

interrupt. The acknowledge from the Controller may either be Success or Failure,

depending on the interrupt routine.

MVI46_ERR_SLOTDIS

The module’s slot has been disabled by the Controller

MVI46_ERR_SERVFAIL

The Controller acknowledged the interrupt with Failure

Example

MVIHANDLE Handle;

/* Generate a module interrupt and wait for ack */

if (MVI_SUCCESS == MVIbp_SetModuleInterrupt(Handle))

printf("Module Interrupt Successful\n");

else

printf("Module Interrupt Failed\n");
