PeOpenFromMemory
Description
Parse a PE 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 sees an empty Buf instead of 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);
PeOpenFromMemory(&pe, &buf);
// buf is now zeroed.
Success
Returns true; out owns the bytes; *in is zeroed.
Failure
Returns false; the bytes have been freed through the Buf’s allocator; *in is zeroed; out is left zeroed.
