I don't think it's something you should do at postconfiguration - 
location structure is complex and not easily accessible.  There 
are location configuration merge callbacks where you are expected 
to work with location configs and, in particular, can use 
ngx_http_conf_get_module_loc_conf() macro to access a 
configuration of other modules (note though, that order of modules 
may be important in this case).

It's under src/, in C language.

I would rather say it's not a part of the API, and you'd better 
avoid using it directly.
