Hello hackers,
What I'm locking for is how to get the name of a function, into a string po=
inter
for logging purpose as
printf("function called: %s\n", p);
based on a pointer to the function because in our realworld code it looks l=
ike this:
int fun(*module(), ...)
{
char *p =3D ....
printf("calling module %s\n", p);
(*module)(int i);
}
i.e. the function fun() gets only a pointer to a function to be called (one
of around 400 different functions of a shared lib)=20
Any (portable idea)? Thanks
matthias
