5713 * Usage: i = putenv (string)
5717 * where string is of the form <name>=<value>.
5718 * Putenv returns 0 normally, -1 on error (not enough core for malloc).
5720 * Putenv may need to add a new name into the environment, or to
5721 * associate a value longer than the current value with a particular
5722 * name. So, to make life simpler, putenv() copies your entire
5723 * environment into the heap (i.e. malloc()) from the stack
5724 * (i.e. where it resides when your process is initiated) the first
5727 * (history removed, not very interesting. See the "screen" sources.)
