.SH DESCRIPTION

.PP

\fBTk_Init\fR is the package initialization procedure for Tk.

It is normally invoked by the \fBTcl_AppInit\fR procedure

for an application or by the \fBload\fR command.

\fBTk_Init\fR adds all of Tk's commands to \fIinterp\fR

and creates a new Tk application, including its main window.

If the initialization is successful \fBTk_Init\fR returns

\fBTCL_OK\fR;  if there is an error it returns \fBTCL_ERROR\fR.

\fBTk_Init\fR also leaves a result or error message

in \fIinterp->result\fR.

.PP

If there is a variable \fBargv\fR in \fIinterp\fR, \fBTk_Init\fR

treats the contents of this variable as a list of options for the

new Tk application.

The options may have any of the forms documented for the

\fBwish\fR application (in fact, \fBwish\fR uses Tk_Init to process

its command-line arguments).
