NAME¶
rtapi_gfp.h - RTAPI wrappers for linux kernel functionality
SYNTAX¶
#include <rtapi_gfp.h>
enum rtapi_gfp_e;
RTAPI_GFP_xxx
typedef ... rtapi_gfp_t;
DESCRIPTION¶
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.
