Hi all,
In my Photon application I have to read/write files from/to the home
directory of the user. I would like to use the HOME environment variable to
determine that directory. BUT I do not know how to work with environment
variables. Which header files should I include? HOME or $HOME (or neither)
is the correct usage?
Can somebody help me?
Thanks,
Eszter Polczer

The function you want is getenv(). The header is in stdlib.h. Look
at getenv() in the helpviewer docs.
Basically your call will look like this:
char * home_directory;
home_directory = getenv( “HOME” );
