.PP
|
||
|
|
The unw_apply_reg_state()
|
||
|
|
routine updates the register values
|
||
|
|
of a cursor according to the instructions in reg_states_data,
|
||
|
|
which have been obtained by calling unw_reg_states_iterate\&.

.SH RETURN VALUE
|
||
|
|
|
||
|
|

.SH THREAD AND SIGNAL SAFETY
|
||
|
|
|
||
|
|
.PP
|
||
|
|
unw_apply_reg_state()
|
||
|
|
is thread\-safe. If cursor cp
|
||
|
|
is
|
||
|
|
in the local address\-space, this routine is also safe to use from a
|
||
|
|
signal handler.
