errors at times and valid results at other times. The 

InitVXIlibrary

function automatically installs a default handler,

DefaultBusErrorHandler

, when it initializes the NI-VXI software.

Because bus errors can occur at any time, a corresponding enable and
disable function is not possible.

SetSoftResetHandler

 replaces the current Soft Reset

interrupt handler with an alternate handler. A default handler,

DefaultSoftResetHandler

, is automatically installed when

InitVXIlibrary

 initializes the NI-VXI software.

EnableSoftReset

 must be called to enable writes to the Reset bit to

generate interrupts to the local CPU after the 

InitVXIlibrary

 call.

SetSysfailHandler

 replaces the current Sysfail interrupt handler

with an alternate handler. A Sysfail condition detected on the local
CPU generates an interrupt that calls the current Sysfail interrupt
handler. A default handler, 

DefaultSysfailHandler

, is

automatically installed when 

InitVXIlibrary

 initializes the NI-VXI

software. 

EnableSysfail

 must be called to enable Sysfail interrupts

after the 

InitVXIlibrary

 call.

SetSysresetHandler

 replaces the current SYSRESET* interrupt

handler with an alternate handler. The 

InitVXIlibrary

 function

automatically installs a default handler, 

DefaultSysresetHandler

,

when it initializes the NI-VXI software. Your application must then
call 

EnableSysreset

 to enable writes to the Reset bit to generate

interrupts to the local CPU.
