NAME
       Tcl_PutEnv - procedures to manipulate the environment

       #include <tcl.h>

       int
       Tcl_PutEnv(assignment)

       const char *assignment (in)	    Info about environment variable in

_________________________________________________________________

DESCRIPTION
       Tcl_PutEnv sets an environment variable. The information is passed in a
       single  string of the form “NAME=value”.	 This procedure is intended to
       be a stand-in for the UNIX putenv system call. All  Tcl-based  applica‐
       tions  using  putenv should redefine it to Tcl_PutEnv so that they will
       interface properly to the Tcl runtime.
