MachoOpenFromMemory
Description
Parse a Mach-O image from an in-memory byte range – L-value / ownership-transfer form (mirrors VecInsertL).
Takes the caller’s Buf by pointer. The parser snapshots the Buf and zeroes the caller’s *in so any post-call use is an empty Buf rather than a stale alias. Allocator comes from the Buf. The zero-on-take invariant holds on success and failure.
Usage example (from documentation)
Buf buf = BufInit(&alloc);
FileRead(&f, &buf);
MachoOpenFromMemory(&m, &buf);
// buf is now zeroed.
Success
Returns true; out owns the bytes; *in is zeroed.
Failure
Returns false; the bytes have been freed; *in is zeroed; out is left zeroed.
