A common convention in Upstart+NIH is for functions to accept a parent
pointer as in the following example:
Foo *make_foo (const void *parent) __attribute__ ((malloc));
Foo *
make_foo (const void *parent)
{
Foo *foo = nih_new (parent, Foo);
/* ... */
return foo;
}
But, if I'm understanding this correctly (?), using the malloc attribute
here is also invalid iff parent != NULL since nih_new() ultimately saves
the value of foo to the parents context before returning the address of
foo.
