    lockType: number,
    start: bigint,
    len: bigint,
    pid: number,
): LockInfo | null
Check if a lock would be blocked. Returns the blocking lock info, or null. (Used for F_GETLK and for F_SETLK conflict check.)
Parameters

- start: bigint
- len: bigint
- pid: number
Returns LockInfo | null
