NAME
uwx_set_nofr() — disable tracking of floating-point registers
SYNOPSIS
#include <uwx.h>
int uwx_set_nofr(struct uwx_env *env);
DESCRIPTION
uwx_set_nofr()
is part of the Unwind Express Library for Integrity systems; see
uwx(3X).
uwx_set_nofr()
disables the tracking of floating-point registers during the stack unwind process.
This can be used to improve unwind performance for applications that do not
need to inspect the values of the preserved floating-point values.
Tracking of floating-point registers is disabled for the
unwind environment named in the
env
parameter; other unwind environments are not affected.
It is not currently possible to re-enable the tracking of floating-point
registers without creating a new unwind environment.
Parameters
- env
A pointer to an unwind environment object.
RETURN VALUE
uwx_set_nofr()
returns
UWX_OK
on success.
See
uwx(3X)
for error codes.
