I'd like to find the type of an arbitrary expression. Ideally, this
would be in the form of a string, e.g., this doesn't actually work but
something like it would be nice:
#define TYPE_STRING(e) Stringify(typeof e)
But even a compile-time message would be acceptable. Basically I'd
like to walk thru the (fixed number of) actual parameters of a
function, displaying the type of each actual parameter, before they're
cast into the formal parameter types associated with the function
prototype.
E.g., from this:
char *fmt = "%d";
enum { one, two, three } arg1;
/* ... */
my_printf (fmt, arg1 )
I'd like to automatically infer that fmt is a char*, and arg1 is an
enum type, without having to search back in the source for the
appropriate declaration.
Any way to force the compiler to tell me this?
