using linux environment variables such as $USER in c++ applications

[Paolo Carlini]

Hi,

in case you have'nt already solved your problem, you will find a very
nice introduction to those issues in §2.1.6 of "Advanced Linux
Programming" by Mark Mitchell et al. The book is published under the
Open Publication License and its full text may be downloaded from the

Cheers,
Paolo Carlini.
