#include </__w/infuse-sdk/infuse-sdk/infuse-sdk/include/infuse/net/coap.h>

Download a file over COAP from an existing socket.

Parameters

socket	Socket already connected to remote server
resource	Resource path URI, for example "path/to/resource"
file_size	Size of the file that is being downloaded (0 if unknown)
data_cb	Callback run on each data chunk received
user_context	Arbitrary user context for data_cb
working_mem	Memory buffer for sending/receiving packets with
working_size	Size of working_mem in bytes
block_size	COAP block size to use (in bytes, 0 == auto)
timeout_ms	Timeout waiting for each response from server

Return values

>=0	bytes downloaded on success
<0	error code on failure
