Re^3: Using vec() from XS

sv_insert doesn't just insert, it's the guts behind substr and s///. But I see your point.

Non-lvalue use of vec boils down to:

    sv_setuv(TARG, do_vecget(src, offset, size));

which should give you what you want.

...and the lvalue part just builds an SV with some magic attached and returns it. When a set operation is performed on the returned SV, the "set" operation from the magic vtable performs the real set on the original SV (the vector) indirectly That can also be easily replicated in XS code.	[reply]
