This class is used for all I/O operations of buffer capable devices.

Buffer(device::T, samples_count, cyclic::Bool = false) where {T <: AbstractDeviceOrTrigger}

Initializes a new Buffer instance.

Parameters

• device::AbstractDeviceOrTrigger : A device instance (either Device or Trigger to which the buffer belongs
• samples_count : The size of the buffer in samples
• cyclic : If set to true, the buffer is circular

length(buf::Buffer)

Size of this buffer, in bytes.

read(buf::Buffer)

Retrieves the samples contained inside the Buffer.

Returns

• A Vector{Cuchar} containing the samples

write(buf::Buffer, data::Vector{T}) where {T}

Copy the given vector of samples into the buffer

Parameters

• data : The data vector containing the samples to copy

Returns

• The number of bytes written into the buffer

cancel(buf::Buffer)

Cancel the current buffer.

device(buf::Buffer)

Device for the buffer.

poll_fd(buf::Buffer)

Poll_fd for the buffer.

push(buf::Buffer [, samples_count])

Submit the samples contained in this buffer to the hardware.

Parameters

• buf::Buffer : The buffer struct
• samples_count (optional) : The number of samples to submit, default = full buffer

refill(buf::Buffer)

Fetch a new set of samples from the hardware.

set_blocking_mode(buf::Buffer, blocking)

Set the buffer's blocking mode.

Parameters:

• blocking : True if in blocking mode else false.

step(buf::Buffer)

Step size for the buffer.
