.AP int intValue in
Integer value used to initialize or set a Tcl value.
.AP long longValue in
Long integer value used to initialize or set a Tcl value.
.AP Tcl_WideInt wideValue in
Wide integer value used to initialize or set a Tcl value.
.AP Tcl_WideUInt uwideValue in
Unsigned wide integer value used to initialize or set a Tcl value.
.AP Tcl_Size indexValue in
\fTcl_Size\f value used to initialize or set a Tcl value.
In Tcl 8.x, \fTcl_Size\f is actually the same as int.
.AP Tcl_Obj *objPtr in/out
For \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR, \fBTcl_SetWideIntObj\fR,
\fBTcl_SetWideUIntObj\fR, \fBTcl_SetIndexObj\fR,
and \fBTcl_SetBignumObj\fR, this points to the value in which to store an
integral value.  For \fBTcl_GetIntFromObj\fR, \fBTcl_GetLongFromObj\fR,
\fBTcl_GetWideIntFromObj\fR, \fBTcl_GetBignumFromObj\fR, and
\fBTcl_TakeBignumFromObj\fR, this refers to the value from which
to retrieve an integral value.
.AP Tcl_Interp *interp in/out
When non-NULL, an error message is left here when integral value

64-bit integer range (-9223372036854775808 to 9223372036854775807).  Depending
on the platform and the C compiler, the actual type might be
\fBlong long int\fR, or something else.
The \fBmp_int\fR type is a multiple-precision integer type defined
by the LibTomMath multiple-precision integer library.
.PP
The \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR, \fBTcl_NewWideIntObj\fR,
\fBTcl_NewWideUIntObj\fR, \fBTcl_NewIndexObj\fR, and \fBTcl_NewBignumObj\fR
routines each create and return a new Tcl value initialized to the
integral value of the argument.  The returned Tcl value is unshared.
.PP
The \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR, \fBTcl_SetWideIntObj\fR,
\fBTcl_SetWideUIntObj\fR, \fBTcl_SetIndexObj\fR, and \fBTcl_SetBignumObj\fR
routines each set the value of an existing Tcl value pointed to by \fIobjPtr\fR
to the integral value provided by the other argument.  The \fIobjPtr\fR
argument must point to an unshared Tcl value.  Any attempt to set the
value of a shared Tcl value violates Tcl's copy-on-write policy.  Any
existing string representation or internal representation in the unshared
Tcl value will be freed as a consequence of setting the new value.
.PP
The \fBTcl_GetIntForIndex\fR routine attempts to retrieve an index
value from the Tcl value \fIobjPtr\fR.  If the attempt succeeds,
then \fBTCL_OK\fR is returned, and the value is written to the
storage provided by the caller.  The attempt might fail if
\fIobjPtr\fR does not hold an index value.  If the attempt fails,
then \fBTCL_ERROR\fR is returned, and if \fIinterp\fR is non-NULL,
