|
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. |

// 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 |

you would use a real value instead. |

/* |
|
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 Tcl list. |

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 Tcl output of the function would be a list containing both |
|
output values. |

/* |
|
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 Tcl list. |

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 Tcl). Rather, the modified input value shows |
|
up as the return value of the function. Thus, to apply this function |
|
to a Tcl variable you might do this : |
|
|
|
set x [neg $x] |
