snip
so, something like
[EMAIL PROTECTED]:~$ cat t.c
#include <stdio.h>
return foo (int a, int b, int c) {
return a + b + c;
}
int main (int argc, char** argv) {
foo(foo(10,20,30), 2, 3);
foo(4, 5, 6);
foo(7, 8, 8);
return 0;
}
[EMAIL PROTECTED]:~$ cpp -D"foo(a,b,c)=found func(a, [second parm b], c)"
t.c | perl -lne 'print for /\[second parm .*?\]/g'
[second parm int b]
[second parm 20]
[second parm 2]
[second parm 5]
[second parm 8]
Except for the false positive for the function definition that works
fairly well.
