_U_DYN_REGISTER(3) Programming Library _U_DYN_REGISTER(3)NAME
_U_dyn_register -- register unwind-info for dynamically generated code
SYNOPSIS
#include <libunwind.h>
void _U_dyn_register(unw_dyn_info_t *di);
DESCRIPTION
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(3)). 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_reg-
ister() or _U_dyn_cancel()).
THREAD AND SIGNAL SAFETY
_U_dyn_register() is thread-safe but not safe to use from a signal handler.

UNW_FLUSH_CACHE(3) Programming Library UNW_FLUSH_CACHE(3)NAME
unw_flush_cache -- flush cached info
SYNOPSIS
#include <libunwind.h>
void unw_flush_cache(unw_addr_space_t as, unw_word_t lo, unw_word_t hi);
DESCRIPTION
The unw_flush_cache() routine flushes all cached info as it relates to address-range lo to hi (non-inclusive) in the target address-space
as. In addition, all info cached for address-space as that is not tied to a particular code-range is also flushed. For example, the
address of the dynamic registration list is not tied to a code-range and its cached value (if any) is flushed by a call to this routine.
The address range specified by lo and hi should be understood as a hint: unw_flush_cache() may flush more information than requested, but
never less. In other words, unw_flush_cache() may overflush, but not underflush.
As a special case, if arguments lo and hi are both 0, all information cached on behalf of address space as is flushed.
RETURN VALUE
The unw_flush_cache() routine cannot fail and does not return a value.
THREAD AND SIGNAL SAFETY
The unw_flush_cache() routine is thread-safe as well as safe to use from a signal handler.
