Matlab coder generates string without the ending null terminator

Hi,

I want to pass a string to a c function doing this:

str = 'test_app';
coder.ceval('put_string', 'algorithm_name', coder.rref(str));

The generated code looks like this:

 char cv0[14];
  static const char cv1[8] = { 't', 'e', 's', 't', '_', 'a', 'p', 'p' };

  static const char cv2[14] = { 'a', 'l', 'g', 'o', 'r', 'i', 't', 'h', 'm', '_',
    'n', 'a', 'm', 'e' };
    
for (i0 = 0; i0 < 14; i0++) {
    cv0[i0] = cv2[i0];
  }

  put_string(cv0, cv1);

How can I convince the coder to add the ending null terminator? I know this is a C/C++ convention but I'm trying to generate code for C here.

Thank you,

Bogdan
