Hi!
Let's assume that I write function that will return
struct buffer_head *, and want also signal about error
can I use ERR_PTR mechanizm for this?
And more general question, when ERR_PTR bad decision,
and when not?
I see some places in kernel, with such functions:
struct foo *f(int *err)
{
*err = ESOMERR;
return NULL;
}
why so?
