.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
\fBTcl_PutEnv\fR sets an environment variable. The information is
|
||
|
|
passed in a single string of the form
|
||
|
|
.QW \fINAME\fB=\fIvalue\fR .
|
||
|
|
This procedure is
|
||
|
|
intended to be a stand-in for the UNIX \fBputenv\fR system call. All
|
||
|
|
Tcl-based applications using \fBputenv\fR should redefine it to
|
||
|
|
\fBTcl_PutEnv\fR so that they will interface properly to the Tcl
|
||
|
|
runtime.
