 '\" The definitions below are for supplemental macros used in Tcl/Tk

 '\" .AP type name in/out ?indent?
 '\"	Start paragraph describing an argument to a library procedure.
 '\"	type is type of argument (int, etc.), in/out is either "in", "out",

 '\"	and indent is equivalent to second arg of .IP (shouldn't ever be
 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?
 '\"	Give maximum sizes of arguments for setting tab stops.  Type and

 to get an integer or long integer value; if \fIobjPtr\fR does not
 already point to an integer object (or a wide integer object in the

 .SH DESCRIPTION
 .PP
 These procedures are used to create, modify, and read
 integer and wide integer Tcl objects from C code.
 \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR,
 \fBTcl_SetIntObj\fR, and \fBTcl_SetLongObj\fR
 create a new object of integer type
 or modify an existing object to have integer type,
 .VS 8.4
 and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR create a new
 object of wide integer type or modify an existing object to have wide
 integer type.
 .VE 8.4
 \fBTcl_NewIntObj\fR and \fBTcl_SetIntObj\fR set the object to have the
 integer value given by \fIintValue\fR,
 \fBTcl_NewLongObj\fR and \fBTcl_SetLongObj\fR
 set the object to have the
 long integer value given by \fIlongValue\fR,
 .VS 8.4
 and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR set the object
 to have the wide integer value given by \fIwideValue\fR.
 \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR and \fBTcl_NewWideIntObj\fR
 return a pointer to a newly created object with reference count zero.
 These procedures set the object's type to be integer
 and assign the integer value to the object's internal representation
 \fIlongValue\fR or \fIwideValue\fR member (as appropriate).
 \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR
 and \fBTcl_SetWideIntObj\fR
 .VE 8.4
 invalidate any old string representation and,
 if the object is not already an integer object,
 free any old internal representation.
 .PP
 \fBTcl_GetIntFromObj\fR and \fBTcl_GetLongFromObj\fR
 attempt to return an integer value from the Tcl object \fIobjPtr\fR,
 .VS 8.4
 and \fBTcl_GetWideIntFromObj\fR attempts to return a wide integer
 value from the Tcl object \fIobjPtr\fR.
 If the object is not already an integer object,
 or a wide integer object in the case of \fBTcl_GetWideIntFromObj\fR
 .VE 8.4
 they will attempt to convert it to one.
 If an error occurs during conversion, they return \fBTCL_ERROR\fR
 and leave an error message in the interpreter's result object
 unless \fIinterp\fR is NULL.
 Also, if the long integer held in the object's internal representation
 \fIlongValue\fR member can not be represented in a (non-long) integer,
 \fBTcl_GetIntFromObj\fR returns \fBTCL_ERROR\fR
 and leaves an error message in the interpreter's result object
 unless \fIinterp\fR is NULL.
 Otherwise, all three procedures return \fBTCL_OK\fR and
 store the integer, long integer value
 .VS 8.4
 or wide integer in the address given by \fIintPtr\fR, \fIlongPtr\fR
 and \fIwidePtr\fR
 .VE 8.4
 respectively.  If the object is not already an integer or wide integer
 object, the conversion will free any old internal representation.

	.SH DESCRIPTION
	.PP
	These procedures are used to create, modify, and read
	integer and wide integer Tcl objects from C code.
	\fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR,
	\fBTcl_SetIntObj\fR, and \fBTcl_SetLongObj\fR
	create a new object of integer type
	or modify an existing object to have integer type,
	.VS 8.4
	and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR create a new
	object of wide integer type or modify an existing object to have wide
	integer type.
	.VE 8.4
	\fBTcl_NewIntObj\fR and \fBTcl_SetIntObj\fR set the object to have the
	integer value given by \fIintValue\fR,
	\fBTcl_NewLongObj\fR and \fBTcl_SetLongObj\fR
	set the object to have the
	long integer value given by \fIlongValue\fR,
	.VS 8.4
	and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR set the object
	to have the wide integer value given by \fIwideValue\fR.
	\fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR and \fBTcl_NewWideIntObj\fR
	return a pointer to a newly created object with reference count zero.
	These procedures set the object's type to be integer
	and assign the integer value to the object's internal representation
	\fIlongValue\fR or \fIwideValue\fR member (as appropriate).
	\fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR
	and \fBTcl_SetWideIntObj\fR
	.VE 8.4
	invalidate any old string representation and,
	if the object is not already an integer object,
	free any old internal representation.
	.PP
	\fBTcl_GetIntFromObj\fR and \fBTcl_GetLongFromObj\fR
	attempt to return an integer value from the Tcl object \fIobjPtr\fR,
	.VS 8.4
	and \fBTcl_GetWideIntFromObj\fR attempts to return a wide integer
	value from the Tcl object \fIobjPtr\fR.
	If the object is not already an integer object,
	or a wide integer object in the case of \fBTcl_GetWideIntFromObj\fR
	.VE 8.4
	they will attempt to convert it to one.
	If an error occurs during conversion, they return \fBTCL_ERROR\fR
	and leave an error message in the interpreter's result object
	unless \fIinterp\fR is NULL.
	Also, if the long integer held in the object's internal representation
	\fIlongValue\fR member can not be represented in a (non-long) integer,
	\fBTcl_GetIntFromObj\fR returns \fBTCL_ERROR\fR
	and leaves an error message in the interpreter's result object
	unless \fIinterp\fR is NULL.
	Otherwise, all three procedures return \fBTCL_OK\fR and
	store the integer, long integer value
	.VS 8.4
	or wide integer in the address given by \fIintPtr\fR, \fIlongPtr\fR
	and \fIwidePtr\fR
	.VE 8.4
	respectively. If the object is not already an integer or wide integer
	object, the conversion will free any old internal representation.
