(Integrity Systems Only)

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.
