unw_get_accessors3

Usage

Overview

The unw_get_accessors() routine returns a pointer to a unw_accessors_t structure, which contains the callback routines that were specified when address space as was created (see unw_create_addr_space(3libunwind)). The returned pointer is guaranteed to remain valid until address space as is destroyed by a call to unw_destroy_addr_space(3libunwind).

Note that unw_get_accessors() can be used to retrieve the callback 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.
