rtapi_firmware(3rtapi)

rtapi_firmware3rtapi

Rtapi wrappers for linux kernel functionality

Usage

#include <rtapi_firmware.h>

struct rtapi_firmware;

int rtapi_request_firmware(const struct rtapi_firmware **fw,
const char *name, struct rtapi_device *device);

void rtapi_release_firmware(const struct rtapi_firmware *fw);

Overview

In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available.

In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation--possibly with reduced functionality--is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)

Realtime considerations

Typically, these functions may be called from realtime init/cleanup code.

Return value

As in Linux.
