NAME
       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 allocated 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.
