Detailed Description

RTDM device.

This structure specifies a RTDM device. As some fields, especially the reserved area, will be modified by RTDM during runtime, the structure must not reside in write-protected memory.

Field Documentation

rtdm_open_handler_t rtdm_device::open_rt

Named device instance creation for real-time contexts, optional (but deprecated) if open_nrt is non-NULL, ignored for protocol devices.

Deprecated:

Only use non-real-time open handler in new drivers.

Referenced by rtdm_dev_register().

rtdm_socket_handler_t rtdm_device::socket_rt

Protocol socket creation for real-time contexts, optional (but deprecated) if socket_nrt is non-NULL, ignored for named devices.

Deprecated:

Only use non-real-time socket creation handler in new drivers.
