Hi,
Is it possible to change the current process's environment variables?
I have looked at `std/process.d` source code, and there is only a private
method `createEnv` used when new (sub)process is created.
In C `putEnv` the answer is positive:
http://man7.org/linux/man-pages/man3/putenv.3.html (FIXME)
I come to this question as I want to set some custom variables for my
unittests. My program reads some tokens from system environments, and
it's convenient if I can simulate different cases for testings.
Thanks for your reading and support.
you can use libc's `putenv()` in D too, it is ok. just import
`core.sys.posix.stdlib`, it is there. D is not antagonistic to C, and
doesn't try to replace the whole libc with it's own libraries. so if you
see something that libc has and you'd like to use -- just do it! ;-)
