Sub-Classes of RTDM_CLASS_MOSTSYNC | |
Currently prepared only for this one subclass. Device naming mechanism must be changed if more subclasses are used.
This way, it's consitent with the Linux MOST driver. | |
| #define | RTDM_SUBCLASS_MOSTSYNC_OASIS 0 |
Defines a device group for MOST Synchronous devices. It doesn't make sense to define a group for MOST in general, because the MOST NetServices part is handled by Linux in a non-realtime way and a device profile should determine how the device is programmed, and a MOST Synchronous device has nothing to do with a MOST Asynchronous device in its programming way.
While a synchronous device handles stream data and is accessed via device files in the Linux driver and the usual read/write calls in the real-time driver, an asynchronous device handles network data and is programmed with sockets.
RTDM_NAMED_DEVICE "mostsync<N>", N >= 0 RTDM_CLASS_MOSTSYNC Definition in file rtmostsync.h.
| #define RTDM_CLASS_MOSTSYNC 15 |
The device class for Synchronous MOST devices. Must be synchronised with addons/rtdm/rtdm.h or RTAI.
Definition at line 85 of file rtmostsync.h.
| #define MOST_SYNC_RT_IOCTL_MAGIC RTDM_CLASS_MOSTSYNC |
Use the RTDM_CLASS_MOSTSYNC magic number for IOCTLs.

Setup ioctl() call. Performs following tasks:
This stops ALL reception on this device. The function call make take some while because it has to wait until each other file has finished the current reading/writing system call.
The function does not allocate any synchronous channels nor does it modify the routing engine. This has to be done with MOST NetServices. The frame_part argument contains the frame part from the view of the MOST PCI card, i.e. it's not the position of the part in the MOST frame but of the routed frames. See the documentation of the routing engine of the OS 8104 for details or the example code which comes with this driver.
Returns 0 on success, a negative error value on failure.
