>From a configuration perspective there's two APIs:

If only .conf files are needed then there is the Asterisk Config Options
API, include/asterisk/config_options.h, which is used by the skeleton
application apps/app_skel.c for configuration parsing, storing, and
usage.

If realtime is needed then there is the Asterisk Sorcery API,
include/asterisk/sorcery.h, which is used by PJSIP and other things -
with the simplest being res/res_mwi_external.c

It's highly recommended to use one of them instead of rolling your own
configuration parsing. They take care of things (such as safe atomic
reloads).

The "safe string copy" you are thinking of is probably ast_copy_string.
