viAssertIntrSignal
Syntax
viAssertIntrSignal(ViSession vi, ViInt16 mode, ViUInt32 statusID);
Description
Asserts the specified device interrupt or signal. This operation can be used to assert a device interrupt condition. In VXI, for example, this can be done with either a VXI signal or a VXI interrupt. On certain bus types, the statusID parameter may be ignored.
Note: This function is not implemented in Agilent VISA.
Parameters
|
Name |
Dir |
Type |
Description |
|
vi |
IN |
ViSession |
Unique logical identifier to a session. |
|
mode |
IN |
ViInt16 |
This specifies how to assert the interrupt. See the Description section for actual values. |
|
statusID |
IN |
ViUInt32 |
This is the status value to be presented during an interrupt acknowledge cycle. |
Special Values for mode Parameter
|
mode |
Action Description |
|
VI_ASSERT_IRQ1 - VI_ASSERT_IRQ7 |
VXI/VME IRQ line. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism. |
|
VI_ASSERT_SIGNAL |
Send the notification via a VXI signal. |
|
VI_ASSERT_USE_ASSIGNED |
Use whatever notification method that has been assigned to the local device. |
Return Values
|
Type ViStatus |
This is the function return status. It returns either a completion code or an error code as follows. |
|
Completion Code |
Description |
|
VI_SUCCESS |
Operation completed successfully. |
|
Error Codes |
Description |
|
VI_ERROR_BERR |
Bus error occurred during transfer. |
|
VI_ERROR_INTR_PENDING |
An interrupt is still pending from a previous call. |
|
VI_ERROR_INV_MODE |
The value specified by the mode parameter is invalid. |
|
VI_ERROR_INV_SESSION |
The given session or object reference is invalid (both are the same value). |
|
VI_ERROR_NSUP_INTR |
The interface cannot generate an interrupt on the requested level or with the requested statusID value. |
|
VI_ERROR_NSUP_MODE |
The specified mode is not supported by this VISA implementation. |
|
VI_ERROR_NSUP_OPER |
The given vi does not support this operation. |
|
VI_ERROR_RSRC_LOCKED |
Specified operation could not be performed because the resource identified by vi has been locked for this kind of access. |
