Fifo.destroy()

Overview

This method destroys the Fifo and frees associated resources. This must be called for every Fifo created.

Syntax

fifo.destroy()

Parameters

None.

Return

None

Raises

Exception with a status code from Status if underlying function calls return a status other than Status.OK.

Notes

• All elements must be removed from the Fifo before calling this method.
  • For input Fifos (type FifoType.HOST_WO), elements are removed by calling Graph.queue_inference().
  • For output Fifos (type FifoType.HOST_RO), elements are removed by calling Fifo.read_elem().

Example

from mvnc import mvncapi

#
# Open a Device, create a Graph, and load graph data from file...
#

# Allocate the Graph and create and allocate two associate Fifos for input and output
input_fifo, output_fifo = graph.allocate_with_fifos(device, graph_buffer)
#
# Use the Fifos...
#

# Destroy the Fifos
input_fifo.destroy()
output_fifo.destroy()

#
# Perform other clean up...
