To which type does SWIG maps C++ signed char * type in Python? -

i need pass non null terminating buffer python c++. i'm using parameter of signed char* type instead of char* since latter converted null terminating string. python interface generated using swig (2.0.1). no typemaps applied swig should use default mapping. when i'm trying use method following error:

notimplementederror: wrong number or type of arguments overloaded function

as buffer tried passing both string , bytearray objects. in both cases mentioned error.

so if have function in c++ type of object should pass in python ?

void set_value(signed char *buffer, int size)

you might able inline wrapper accepts c++ string (which not null terminated), this:

%include <std_string.i> %inline %{     void set_value_str(const std::string& str) { set_value(str.c_str(), str.size()); } %} 

the std_string.i defines typemaps allow call set_value_str python string argument. don't know if typemap uses char array version of std::string constructor, invalidate approach if buffer can contain null bytes.

note: can name wrapper set_value, doesn't have different name.
