unw_get_accessors −− get pointer to accessor call−backs
#include <libunwind.h>
unw_accessors_t *unw_get_accessors(unw_addr_space_t as);
The unw_get_accessors() routine returns a pointer to a unw_accessors_t structure, which contains the call−back routines that were specified when address space as was created (see unw_create_addr_space(3)). The returned pointer is guaranteed to remain valid until address space as is destroyed by a call to unw_destroy_addr_space(3).
Note that unw_get_accessors() can be used to retrieve the call−back routines for the local address space unw_local_addr_space.
The unw_get_accessors() routine cannot fail and always returns a valid (non−NULL) pointer to an unw_accessors_t structure.
The unw_get_accessors() routine is thread−safe as well as safe to use from a signal handler.
