Re: [cdt-dev] CODAN question for function can not be resolved AND invali

[Tomasz Wesołowski <kosashi@xxxxxxxxx>]

Hola, Felipe,

About the "function cannot be resolved" problem: Please note that C allows calling undefined functions. C++ will not - you should get the warning right after renaming sample.c to sample.cpp.

About the "invalid arguments": The argument 'a' is a char which is implicitly castable to double, so the call h_function('a') is valid. If you try something not castable to double, you'd get the error. Try replacing that call with h_function("str").

Hope that helps. Thank you for the awareness :)

Best regards,
-- Tomasz Wesołowski

Hi all.  First thanks for your help.

 

Do the “function can not be resolved” and the “invalid arguments”  checkers work?

 

I am trying them in a trivial project having the inclusion for both as: src/*.c

 

The code is quite trivial:

 

Sample.h contents:

 

#ifndef SAMPLE_H_

#define SAMPLE_H_

 

int h_function(double param);

void void_func();

#endif /* SAMPLE_H_ */

Sample.c contents:

 

#include <stdlib.h>

#include "Sample.h"

 

int main(void) {

      return EXIT_SUCCESS + h_function('a') + function_that_does_not();

}

int h_function(double param) {

      return 45;

}

 

void void_func() {

      return;

}

 

I was expecting a warning or something similar for the h_function call (it provides a char when a double is declared as the type parameter).

 

On the other hand as the case of referring an undeclared variable I was expecting a warning or something  like that for the not declared function call function_that_does_not.

 

Am I missing something?

 

Best regards and thanks again,
