NAME

rtapi_byteorder - RTAPI wrappers for linux kernel functionality

SYNTAX

#include <rtapi_byteorder.h>

RTAPI_BIG_ENDIAN

Defined to 1 if the platform is big-endian, 0 otherwise.

RTAPI_LITTLE_ENDIAN

Defined to 1 if the platform is little-endian, 0 otherwise.

RTAPI_FLOAT_BIG_ENDIAN

Defined to 1 if the platform double-precision value is big-endian, 0 otherwise.

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_byteorder_register always succeeds)

REALTIME CONSIDERATIONS

May be used at any time.

RETURN VALUE

As in Linux.
