ibonl — close or reinitialize descriptor (board or device)
#include <gpib/ib.h>
int ibonl( | ud, | |
online) ; |
int ud
;int online
;
If the online
is zero, then ibonl() frees the
resources associated with the board or device descriptor
ud
. The descriptor cannot be used again after the
ibonl() call.
If the online
is nonzero, then all the settings
associated with the descriptor (GPIB address, end-of-string mode, timeout,
etc.) are reset to their “default” values. The “default” values are
the settings the descriptor had when it was first obtained with
ibdev() or
ibfind().
The value of ibsta is returned.
