.SH NAME
Tcl_Interp \- client-visible fields of interpreter structures
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
typedef struct {
char *\fIresult\fR; /* NO LONGER AVAILABLE */
Tcl_FreeProc *\fIfreeProc\fR; /* NO LONGER AVAILABLE */
int \fIerrorLine\fR; /* NO LONGER AVAILABLE */
} \fBTcl_Interp\fR;
typedef void \fBTcl_FreeProc\fR(
char *\fIblockPtr\fR);
.BE
.SH DESCRIPTION
.PP
The \fBTcl_CreateInterp\fR procedure returns a pointer to a \fBTcl_Interp\fR
structure. Callers of \fBTcl_CreateInterp\fR should use this pointer
as an opaque token, suitable for nothing other than passing back to
other routines in the Tcl interface from the same thread that called
\fBTcl_CreateInterp\fR. The \fBTcl_Interp\fR struct no longer has any
supported client-visible fields. Supported public routines such as
\fBTcl_SetResult\fR, \fBTcl_GetResult\fR, \fBTcl_SetErrorLine\fR,
\fBTcl_GetErrorLine\fR must be used instead.
.PP
Any legacy programs and extensions trying to access the fields above
in their source code will need conversion to compile for Tcl 8.7 and later.
