Nothing to it.  Code your main() as follows:

main (argc, argv, envp)
int  argc;
char *argv[];
char *envp[];
{
/*  etc. */
}

envp stands for ENVironment Pointers.  It's a null terminated array of
pointers to null terminated strings in the format name=value, where name
is the name of the environment variable and value is what it's set to.  It
will contain all the user's currently set environment variables.

Alternatively, you can use the getenv(3) function if you only want to
access some specific environment variables.

As usual, RTFM. (-:
