// modules manage an internal symbol table of type mappings. This

// table keeps track of which types are equivalent to each other. The
|

// ptrmap() function provides a mechanism for scripts to add symbols
|
||||
// to this table. For example :
|
||||
//
|
||||
// ptrmap("double_p","Real_p");
|

//
|

// would make the types "doublePtr" and "RealPtr" equivalent to each
|

// other. Pointers of either type could now be used interchangably.
|

//
|

// Normally this function is not needed, but it can be used to

// circumvent SWIG's normal type-checking behavior or to work around
|

// weird type-handling problems.

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.
|

unsigned long *INPUT

unsigned char *INPUT

double fadd(double *a, double *b) {
|

double fadd(double *INPUT, double *INPUT);

%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 Ruby Array.
|
||||
|
||||
int *OUTPUT
|

short *OUTPUT
|

long *OUTPUT

unsigned int *OUTPUT

unsigned long *OUTPUT
|
||||
unsigned char *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);
|
||||
|
||||

||||
%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.

%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 Ruby array.
|
||||
|
||||
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 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.

Ruby has builtin class Time. INPUT/OUPUT typemap for timeval and

time_t is provided.

int PROG_ARGC

Some C function receive argc and argv from C main function.
|

This typemap provides ignore typemap which pass Ruby ARGV contents
|

as argc and argv to C function.
