-.Sh DESCRIPTION
-The
-.Fn malloc_create_zone
-function creates a malloc zone, advising an initial allocation of
-.Fa start_size
-bytes, and specifying
-.Fa flags
-The returned malloc zone can be used to provide custom allocation and
-deallocation behavior, and to retrieve additional information about the
-allocations in that zone.
-At present there are no client settable flag values recognized by malloc_create_zone(),
-the flags argument should always be passed as zero.
-.Pp
-The
-.Fn malloc_destroy_zone
-function deallocates all memory associated with objects in
-.Fa zone
-as well as
-.Fa zone
-itself.
-.Pp
-The
-.Fn malloc_default_zone
-function returns the default system malloc zone, used by
-.Xr malloc 3 ,
-and
-.Xr free 3 .
-.Pp
-The
-.Fn malloc_zone_from_ptr
-function returns a pointer to the malloc zone which contains
-.Fa ptr
-or NULL, if the pointer does not point to an allocated object in any current
-malloc zone.
-.Pp
-The
-.Fn malloc_zone_malloc ,
-.Fn malloc_zone_calloc ,
-.Fn malloc_zone_valloc ,
-.Fn malloc_zone_realloc ,
-.Fn malloc_zone_memalign ,
-and
-.Fn malloc_zone_free
-perform the same task on
-.Fa zone
-as their non-prefixed variants,
-.Xr malloc 3 ,
-.Xr calloc 3 ,
-.Xr valloc 3 ,
-.Xr realloc 3 ,
-.Xr posix_memalign 3 ,
-and
-.Xr free 3 perform on the default system malloc zone.
-.Sh RETURN VALUES
-The
-.Fn malloc_create_zone ,
-.Fn malloc_default_zone ,
-and
-.Fn malloc_zone_from_ptr
-functions return a pointer to a malloc_zone_t structure, or NULL if there was
-an error.
-.Pp
-The
-.Fn malloc_zone_malloc ,
-.Fn malloc_zone_calloc ,
-.Fn malloc_zone_valloc ,
-.Fn malloc_zone_realloc ,
-and
-.Fn malloc_zone_memalign
-functions return a pointer to allocated memory. If there is an error, they
-return a NULL pointer. They are not required to set
-.Va errno .
