Re: setting getting variable to be changed in production and read in my C module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



actually noone is working "${VAR_NAME}" nor $VAR_NAME nor VAR_NAME

is there anything similar but related to my module?
for instance, now I have mymodule.conf I would prefer to write it there than in the general conf file, is it possible to define my var there and use ap_resolve_env()?

OK, sorry for not having looked at ap_resolve_env() more thoroughly first.

What you'd have to use in your module is in fact:
    const char *var_value = ap_resolve_env(some_pool, "${VAR_NAME}");

This still stands, even worse (prefix + suffix).

But maybe simple enough if you'll only use string literals...
