Declaration

#include <xtos/bci.h>

int xtos_bci_stop(xtos_bci_session_t *session);

Parameter	Type	Description
session	xtos_bci_session_t *	Non-NULL session handle.

Returns 0 and clears streaming after ioctl success; returns -1 while retaining the prior flag on failure.

errno	Condition
EINVAL	session is NULL, or the driver rejects the argument or state.
ENOTTY/EOPNOTSUPP	The device does not support the ioctl or XTOS BCI stop capability.
system errno	Preserves driver or system errno from ioctl failure.

Statistics can still be read after a successful stop; destroy also attempts stop for an active session.
The caller must coordinate acquisition-thread shutdown; the SDK does not wait for other threads.
