Expand description
@brief Performs a blockwise CoAP GET request, store the response in a buffer.
This function will fetch the content of the specified resource path via block-wise-transfer. The blocks will be re-assembled into @p buf
@param[in] sock socket to use for the request @param[in] path pointer to source path @param[in] blksize sender suggested SZX for the COAP block request @param[in] buf Target buffer @param[in] len Target buffer length
@returns <0 on error @returns -EINVAL if an invalid url is provided @returns -ENOBUFS if the provided buffer was too small @returns size of the response payload on success
