RE: [cdt-dev] How to figure out which function is using macro withindex only
|
Dmitry,
a function never uses a macro, however a macro may be used to define
(part of) a function or mutliple functions, see my examples below.
In general you cannot map macro expansions to function definitions.
To figure out the relationship between a macro expansion and function
definitions you'd need to know the file-offsets of the function
definition.
This information is currently not part of the index.
Markus.
Why macro expansions don't map to function definitions:
#define TINT int
#define CALL printf
#define ENTIRE_DEF void func() {}
#define OVERLAP static int sVar; int getBla(){return sVar;} void
setBla(int x){sVar=x;}
void f1() {
CALL("bla"); // ok, CALL is used within f1().
}
TINT f2() {} // is TINT used within f2()??
ENTIRE_DEF // ENTIRE_DEF is used to define func().
OVERLAP // OVERLAP is used to define getBla(), setBla(int) and
more.
