DESCRIPTION

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