/*
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.
*/
// ------------------------------------------------------------------------
// Pointer handling
//
// These mappings provide support for input/output arguments and common
// uses for C/C++ pointers.
// ------------------------------------------------------------------------
// INPUT typemaps.
// These remap a C pointer to be an "INPUT" value which is passed by value
// instead of reference.
/*
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
long long *INPUT
unsigned int *INPUT
unsigned short *INPUT
unsigned long *INPUT
unsigned long long *INPUT
unsigned char *INPUT
bool *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);

// OUTPUT typemaps. These typemaps are used for parameters that
// are output only. The output value is appended to the result as
// a array element.
/*
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 Ruby Array.
int *OUTPUT
short *OUTPUT
long *OUTPUT
long long *OUTPUT
unsigned int *OUTPUT
unsigned short *OUTPUT
unsigned long *OUTPUT
unsigned long long *OUTPUT
unsigned char *OUTPUT
bool *OUTPUT
float *OUTPUT
double *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 Ruby output of the function would be a Array containing both
output values.

// Mappings for an argument that is both an input and output
// parameter
/*
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 Ruby array.
int *INOUT
short *INOUT
long *INOUT
long long *INOUT
unsigned int *INOUT
unsigned short *INOUT
unsigned long *INOUT
unsigned long long *INOUT
unsigned char *INOUT
bool *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 Ruby). Rather, the modified input value shows
up as the return value of the function. Thus, to apply this function
to a Ruby 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.
