RTAPI_SLAB(3)

NAME
rtapi_slab - 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.
