TimeOut
Syntax INT WINAPI TimeOut(DevHandleT devHandle, DWORD millisec);
devHandle refers to either an IEEE 488 interface or an external device.
millisec is a numeric value given in milliseconds.
Returns -1 if error
Bus States None
Example errorcode = TimeOut(ieee,100); Sets the timeout value to 100 msec.
See Also TimeOutQuery, Reset
The TimeOut command sets the number of milliseconds that Driver488 waits for a transfer before
declaring a timeout error. The timeout value sets a limit on the total time allowed for an operation. For
example, when using the Enter command all expected data must be received within the specified timeout
period or a timeout error will occur.
Timeout checking may be suppressed by specifying a timeout value of zero seconds. The zero seconds
specification results in a timeout period of about 49 days.
