I am trying to use the QBSBlit() routine. In Volume 2 of my RKM it says
that this routine takes a "pointer to a blit structure" as its argument.
That document also points me to the man page for QBlit which, in turn,
points me to the header file blit.h. In my copy of the Mortimore book
it says that this routine takes a pointer to a "struct BlitNode" as its
argument. In Volume 1 one of the RKM it tells me that it takes a pointer
to a "struct bltnode".
So, having gotten past the conflicting names, I look into blit.h and find
that a struct bltnode looks like this:
struct bltnode
{
struct bltnode *n;
int (*function)();
char stat;
short blitsize;
short beamsync;
int (*cleanup)();
};
However, the structure shown in both the Mortimore book and the RKM omits
the blitsize field, and I cannot find it described in the text.
What should this field contain? What uses it? How is it used?
Is it time for me to get a new set of manuals?
