Detailed Description

A zero-copy interface for transport objects. Provides a way to get send and receive buffers with memory managed by the transport object.

Member Typedef Documentation

sptr

typedef std::shared_ptr<zero_copy_if> uhd::transport::zero_copy_if::sptr

Constructor & Destructor Documentation

~zero_copy_if()

virtual uhd::transport::zero_copy_if::~zero_copy_if ( )

inlinevirtual

Clean up tasks before releasing the transport object.

Member Function Documentation

get_num_recv_frames()

virtual size_t uhd::transport::zero_copy_if::get_num_recv_frames ( void  ) const

pure virtual

Get the number of receive frames: The number of simultaneous receive buffers in use.

Returns

number of frames

get_num_send_frames()

virtual size_t uhd::transport::zero_copy_if::get_num_send_frames ( void  ) const

pure virtual

Get the number of send frames: The number of simultaneous send buffers in use.

Returns

number of frames

get_recv_buff()

virtual managed_recv_buffer::sptr uhd::transport::zero_copy_if::get_recv_buff ( double  timeout = 0.1 )

pure virtual

Get a new receive buffer from this transport object.

Parameters

timeout

the timeout to get the buffer in seconds

Returns

a managed buffer, or null sptr on timeout/error

get_recv_frame_size()

virtual size_t uhd::transport::zero_copy_if::get_recv_frame_size ( void  ) const

pure virtual

Get the size of a receive frame: The maximum capacity of a single receive buffer.

Returns

frame size in bytes

get_send_buff()

virtual managed_send_buffer::sptr uhd::transport::zero_copy_if::get_send_buff ( double  timeout = 0.1 )

pure virtual

Get a new send buffer from this transport object.

Parameters

timeout

the timeout to get the buffer in seconds

Returns

a managed buffer, or null sptr on timeout/error

get_send_frame_size()

virtual size_t uhd::transport::zero_copy_if::get_send_frame_size ( void  ) const

pure virtual

Get the size of a send frame: The maximum capacity of a single send buffer.

Returns

frame size in bytes
