wrapper code. This provides access to scripting-specific
variables in the wrapper function.
2.7 SWIG-1.3.10 features a total rewrite of the typemap system.
Typemaps now use a different variable naming scheme. Typemaps
for arguments look like this:
%typemap(in) sometype {
$1 = convert value ($input);
}
The variable $1 replaces $target and the variable $input replaces
$source.
For output values, typemaps look like this:
%typemap(out) sometype {
$result = create result ($1);
}
The variable $1 replaces $source and the variable $result replaces
$target.
See Doc/Manual/Typemaps.html for a full description of the new
typemap system.
2.8 Multi-argument typemaps are now supported. This solves a common
problem that occurs with functions like this
void foo(char *buffer, int len);
where you would like to make the two arguments operate as a single
object in the target language.
