#   (2) This script targets any POSIX shell, so it avoids extensions provided

#       The "traditional" practice of packing multiple parameters into a
#       space-separated string is a well documented source of bugs and security
#       problems, so this is (mostly) avoided, by progressively accumulating
#       options in "$@", and eventually passing that to Java.

Em seguida, tente com o velho amigo do programador, o preenchimento automático do editor.

Você digita o primeiro parâmetro da função, `first_name`, depois um ponto (`.`) e, em seguida, pressiona `Ctrl + Space` para acionar a conclusão.

Mas, infelizmente, você não obtém nada útil:

// If there is not enough space the pool will return 0 bytes available.
// The size of each will be multiplied by the number of sets.
// Negative sizes are seen as 0 bytes.

তারপর, আপনি পুরোনো প্রোগ্রামারের বন্ধু, এডিটর অটোকমপ্লিশনের সাহায্যে নেওয়ার চেষ্টা করেন।

আপনি ফাংশনের প্রথম প্যারামিটার `first_name` টাইপ করেন, তারপর একটি ডট (`.`) টাইপ করেন এবং `Ctrl+Space` চাপেন অটোকমপ্লিশন ট্রিগার করার জন্য।

কিন্তু, দুর্ভাগ্যবশত, আপনি কিছুই উপযোগী পান না:

### টাইপ যোগ করুন

আসুন আগের সংস্করণ থেকে একটি লাইন পরিবর্তন করি।

    }
