Hi,
what is the preferred way to get at another process's environment
variables? /proc/$$/environ looks like the most portable way [across all
arches Linux runs on], but it cannot easily be mmap'ed because the size
is not known. In fact, mmap does not seem to work at all on that file.
So I would have to allocate a large buffer (4K is the limit for procfs
files AFAICR) to potentially hold big environments, which does not sound
really wise either. Or is it the best choice available?
