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.

AUTHOR

The Unwind Express Library was developed by Hewlett-Packard.
