int eid;

HP-UX COMPATIBILITY

Level: Device I/O Library − HP-UX/EXTENDED

Origin: HP

DESCRIPTION

Io_reset resets the interface associated with the device file that was opened. It also pulses the peripheral reset line on the GPIO interface, or the IFC line on the HP-IB. Eid is an entity identifier of an open HP-IB raw bus device file obtained from an open(2), dup(2), fcntl(2), or creat(2) call.

Io_reset also causes an interface to go through its self-test, and returns a failure indication if the interface fails its test.

RETURN VALUE

Io_reset returns 0 (zero) if successful, or −1 if an error was encountered.
