_U_dyn_register3

Usage

Overview

The _U_dyn_register() routine registers unwind info for a dynamically generated procedure. The procedure's unwind info is described by a structure of type unw_dyn_info_t (see libunwind-dynamic(3libunwind)). A pointer to this structure is passed in argument di.

The _U_dyn_register() routine is guaranteed to execute in constant time (in the absence of contention from concurrent calls to _U_dyn_register() or _U_dyn_cancel()).

Thread and signal safety

_U_dyn_register() is thread safe but not safe to use from a signal handler.
