Bug

pkg/internal/table.go:187 uses C.ulong(len(ipcBytes)) but the C header declares the parameter as size_t:

// include/lancedb.h
struct SimpleResult *simple_lancedb_table_add_ipc(void *table_handle,
                                                  const uint8_t *ipc_data,
                                                  size_t ipc_len,  // <--
                                                  int64_t *added_count);

On Windows (LLP64), unsigned long is 32-bit but size_t is 64-bit, so the types don't match.

Fix

-		C.ulong(len(ipcBytes)),
+		C.size_t(len(ipcBytes)),

C.size_t is already used correctly in table.go:92 and connection.go:193.

Environment

• Go 1.25, Windows, MinGW (GitHub Actions windows-latest)
• lancedb-go v0.1.2
