NAME
uwx_register_alloc_cb() — register custom allocate and free callbacks
SYNOPSIS
#include <uwx.h>
int uwx_register_alloc_cb(
alloc_cballoc,
free_cbfree
);
DESCRIPTION
uwx_register_alloc_cb()
is part of the Unwind Express Library for Integrity systems; see
uwx(3X).
uwx_register_alloc_cb()
registers custom allocate and free callbacks for use by the Unwind Express Library.
By default, the Unwind Express Library uses
malloc()
and
free()
(see
malloc(3C))
to allocate and deallocate memory dynamically as needed.
Custom callback routines having the same function prototypes may be registered at any time,
and take effect for subsequent unwind environments created by calls to
uwx_init().
Unwind environments already created but not yet freed will not be affected by
this call, so a call to
uwx_free()
will use the free routine that was in effect when that unwind environment was created.
Parameters
- alloc
A pointer to a custom callback routine for dynamic memory allocation.
This function must have the same prototype as the standard
malloc()
function.
- free
A pointer to a custom callback routine for dynamic memory deallocation.
This function must have the same prototype as the standard
free()
function.
RETURN VALUE
uwx_register_alloc_cb()
returns
UWX_OK
on success.
See
uwx(3X)
for error codes.
