Accessing string values from octave_value

[Shamika Mohanan]

Hello,

How do I access string values from octave_value and octave_value_list?

I have the following code written in c++

octave_value path_dir=feval("pwd");
std::string pd  = path_dir.string_value ();
std::cout <<pd<< std::endl;

When I run this code, I get the following error-

octave_base_value::convert_to_str_internal (): wrong type argument 'cs-list'

How do I resolve this error?

Regards,

Shamika
