11 int unw_apply_reg_state(unw_cursor_t *cp, void *reg_states_data);
12
14 The unw_apply_reg_state() routine updates the register values of a cur‐
15 sor according to the instructions in reg_states_data, which have been
16 obtained by calling unw_reg_states_iterate.
17
19 On successful completion, unw_apply_reg_state() returns 0. Otherwise
20 the negative value of one of the error-codes below is returned.
21
23 unw_apply_reg_state() is thread-safe. If cursor cp is in the local
24 address-space, this routine is also safe to use from a signal handler.
25
27 UNW_EUNSPEC
28 An unspecified error occurred.

30 UNW_ENOINFO
31 Libunwind was unable to locate unwind-info for the procedure.
32
33 UNW_EBADVERSION
34 The unwind-info for the procedure has version or format that is
35 not understood by libunwind.
36
37 In addition, unw_apply_reg_state() may return any error returned by the
38 access_mem() call-back (see unw_create_addr_space(3)).
