NAME

       rtapi_slab.h - RTAPI wrappers for linux kernel functionality

SYNTAX

       #include <rtapi_slab.h>

       void *rtapi_kmalloc(size_t size, gfp_t g);

       void *rtapi_kzalloc(size_t size, gfp_t g);

       void *rtapi_krealloc(size_t size, gfp_t g);

       void rtapi_kfree(void *);

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

       Call  only  from  within init/cleanup code, not from realtime tasks.  This function is not available from
       non-realtime code.

RETURN VALUE

       As in Linux.
