The SWIG typemap library provides a language independent mechanism for
|
|
supporting output arguments, input values, and other C function
|
|
calling mechanisms. The primary use of the library is to provide a
|
|
better interface to certain C function--especially those involving
|
|
pointers.

%subsection "Input Methods"
|
|
|
|
%text %{
|
|
The following methods can be applied to turn a pointer into a simple
|
|
"input" value. That is, instead of passing a pointer to an object,
|
|
you would use a real value instead.
|
|
|
|
int *INPUT
|
|
short *INPUT
|
|
long *INPUT
|
|
unsigned int *INPUT
|
|
unsigned short *INPUT
|
|
unsigned long *INPUT
|
|
unsigned char *INPUT
|
|
float *INPUT
|
|
double *INPUT
|
|
|
|
To use these, suppose you had a C function like this :
|
|
|
|
double fadd(double *a, double *b) {
|
|
return *a+*b;
|
|
}
|
|
|
|
You could wrap it with SWIG as follows :
|
|
|
|
%include typemaps.i
|
|
double fadd(double *INPUT, double *INPUT);
|
|
|
|
or you can use the %apply directive :
|
|
|
|
%include typemaps.i
|
|
%apply double *INPUT { double *a, double *b };
|
|
double fadd(double *a, double *b);
|
|
|
|
%}

|
%subsection "Output Methods"
|
|
|
|
%text %{
|
|
The following methods can be applied to turn a pointer into an "output"
|
|
value. When calling a function, no input value would be given for
|
|
a parameter, but an output value would be returned. In the case of
|
|
multiple output values, they are returned in the form of a Python tuple.
|
|
|
|
int *OUTPUT
|
|
short *OUTPUT
|
|
long *OUTPUT
|
|
unsigned int *OUTPUT
|
|
unsigned short *OUTPUT
|
|
unsigned long *OUTPUT
|
|
unsigned char *OUTPUT
|
|
float *OUTPUT
|
|
double *OUTPUT
|
|
|
|
A Python List can also be returned by using L_OUTPUT instead of OUTPUT.
|
|
|
|
For example, suppose you were trying to wrap the modf() function in the
|
|
C math library which splits x into integral and fractional parts (and
|
|
returns the integer part in one of its parameters).K:
|
|
|
|
double modf(double x, double *ip);
|
|
|
|
You could wrap it with SWIG as follows :
|
|
|
|
%include typemaps.i
|
|
double modf(double x, double *OUTPUT);
|
|
|
|
or you can use the %apply directive :
|
|
|
|
%include typemaps.i
|
|
%apply double *OUTPUT { double *ip };
|
|
double modf(double x, double *ip);
|
|
|
|
The Python output of the function would be a tuple containing both
|
|
output values.

%subsection "Input/Output Methods"
|
|
|
|
%text %{
|
|
The following methods can be applied to make a function parameter both
|
|
an input and output value. This combines the behavior of both the
|
|
"INPUT" and "OUTPUT" methods described earlier. Output values are
|
|
returned in the form of a Python tuple. To return a Python list,
|
|
using L_INOUT instead.
|
|
|
|
int *INOUT
|
|
short *INOUT
|
|
long *INOUT
|
|
unsigned int *INOUT
|
|
unsigned short *INOUT
|
|
unsigned long *INOUT
|
|
unsigned char *INOUT
|
|
float *INOUT
|
|
double *INOUT
|
|
|
|
For example, suppose you were trying to wrap the following function :
|
|
|
|
void neg(double *x) {
|
|
*x = -(*x);
|
|
}
|
|
|
|
You could wrap it with SWIG as follows :
|
|
|
|
%include typemaps.i
|
|
void neg(double *INOUT);
|
|
|
|
or you can use the %apply directive :
|
|
|
|
%include typemaps.i
|
|
%apply double *INOUT { double *x };
|
|
void neg(double *x);
|
|
|
|
Unlike C, this mapping does not directly modify the input value (since
|
|
this makes no sense in Python). Rather, the modified input value shows
|
|
up as the return value of the function. Thus, to apply this function
|
|
to a Python variable you might do this :
|
|
|
|
x = neg(x)
|
|
|
|
Note : previous versions of SWIG used the symbol 'BOTH' to mark
|
|
input/output arguments. This is still supported, but will be slowly
|
|
phased out in future releases.

The typemaps.i library also provides the following mappings :
|
|
|
|
PyObject *
|
|
|
|
When a PyObject * appears as either an input value or return
|
|
value of a function, SWIG passes it through unmodified. Thus,
|
|
if you want to write a C function that operates on PyObjects,
|
|
it is easy to write. For example :
|
|
|
|
%include typemaps.i
|
|
PyObject *spam(PyObject *obj1, int n);
|
|
|
|
Unlike normal Python wrapper functions, These functions can
|
|
use any combination of parameters that you wish.

// If a PyObject * appears as either an argument or a function return
|
|
// value, simply pass it straight through.
