Could argument names be included in warning messages when they are available?
This is the present output:
$ g++ -Wall -o t main.cpp
main.cpp: In function int main():
main.cpp:12: warning: passing NULL to non-pointer argument 2 of void f(int,
bool, bool, int, unsigned int)
main.cpp:12: warning: passing NULL to non-pointer argument 3 of void f(int,
bool, bool, int, unsigned int)
The 3rd argument is called "rangetype", so that could be included, to give more
context to the user.
If the name is available, it could be included, for example as this output:
$ g++ -Wall -o t main.cpp
main.cpp: In function int main():
main.cpp:12: warning: passing NULL to non-pointer argument 2 of void f(int,
bool, bool, int, unsigned int)
main.cpp:12: warning: passing NULL to non-pointer argument 3 'rangetype' of
void f(int, bool, bool, int, unsigned int)
Example program:
// g++ -Wall -o t main.cpp
#include <string.h>
void f(int, bool, bool rangetype, int, unsigned int)
{
int i = 1;
if(rangetype) i =2;
}
int main()
{
f(0,NULL,NULL, 1, 1);
}
