NAME

       ibstop - abort asynchronous i/o operation (board or device)

SYNOPSIS

       #include <gpib/ib.h>

       int ibstop(int ud);

DESCRIPTION

       ibstop() aborts an asynchronous i/o operation (for example, one started with ibcmda(), ibrda(), or
       ibwrta()).

       The return value of ibstop() is counter-intuitive. On successfully aborting an asynchronous operation,
       the ERR bit is set in ibsta, and iberr is set to EABO. If the ERR bit is not set in ibsta, then there was
       no asynchronous i/o operation in progress. If the function failed, the ERR bit will be set and iberr will
       be set to some value other than EABO.

RETURN VALUE

       The value of ibsta is returned.
