DESCRIPTION

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