char** Ns_CopyEnviron

(

Ns_DString *

(

void

int NsTclEnvCmd	(	ClientData	dummy,
		Tcl_Interp *	interp,
		int	argc,
		char **	argv
	)

----------------------------------------------------------------------

NsTclEnvCmd --

Implement the "env" command. Read the code to see what it does. NOTE: The getenv() and putenv() routines are assumed MT safe and there's no attempt to avoid the race condition between finding a variable and using it. The reason is it's assumed the environment would only be modified, if ever, at startup.

Results: A standard Tcl result.

Side effects: Environment variables may be updated.
