getenv, putenv - access environment variables
SYNOPSIS
#include <u.h>
#include <libc.h>
char* getenv(char *name)
int putenv(char *name, char *val)
DESCRIPTION
Getenv reads the contents of /env/name (see env(3)) into memory allo‐
cated with malloc(2), 0-terminates it, and returns a pointer to that
area. If no file exists, 0 is returned.
Putenv creates the file /env/name and writes the string val to it. The
terminating 0 is not written. If the file value cannot be written, -1
is returned.
