Hi Justin,
In MATLAB, when passing and receiving char* parameters to and from C++ functions using 'calllib' function, you need to handle them as MATLAB strings (char arrays).
Here is how you can modify your MATLAB code:
% Define the input parameters
index = 1;
strOutParameter = blanks(256);
% Call the C++ function using calllib
[intReturned, strOutParameter] = calllib('myLib', 'myfunction', index, strOutParameter);
% Convert the output parameter to a string
strOutParameter = strtrim(strOutParameter);
where,
- blanks(256) return 1-by-n array of space characters.
- strtrim is used to remove any trailing whitespace characters from the output parameter.
Please refer to the below documentations for more details on:
