unw_get_accessors -- get pointer to accessor call-backs

Synopsis

#include <libunwind.h>

unw_accessors_t *unw_get_accessors(unw_addr_space_t as);

Description

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.

Return Value

The unw_get_accessors() routine cannot fail and always  returns a valid (non-NULL) pointer to an  unw_accessors_t structure.

Thread and Signal Safety

The unw_get_accessors() routine is thread-safe as well as  safe to use from a signal handler.
