KMEM_FREE(9)           NetBSD Kernel Developer's Manual           KMEM_FREE(9)


NAME

     kmem_free -- free kernel wired memory


SYNOPSIS

     #include <sys/kmem.h>

     void
     kmem_free(void *p, size_t size);


DESCRIPTION

     kmem_free() frees kernel wired memory allocated by kmem_alloc() or
     kmem_zalloc() so that it can be used for other purposes.  It takes the
     following arguments.

     p        The pointer to the memory being freed.  It must be the one
              returned by kmem_alloc() or kmem_zalloc().

     size     The size of the memory being freed, in bytes.  It must be the
              same as the size argument used for kmem_alloc() or kmem_zalloc()
              when the memory was allocated.

     Freeing NULL is illegal.

CAVEATS

     kmem_free() can not be used from interrupt context.
