Tcl_PutEnv - procedures to manipulate the environment
- const char *assignment (in)
- Info about environment variable in the format
“NAME=value”. The assignment
argument is in the system encoding.
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 applications using putenv should redefine it to
Tcl_PutEnv so that they will interface properly to the Tcl runtime.
