Binary Put/Get for Strings (with Unicode)
English:
نقل قول:More information: These functions allow you to write and read (put/get) strings to/from a file opened in binary-mode. A unicode-version is also included. All functions let you specify if you want to use a integer or long length-descriptor. If you choose integer the resulting file will be 2 bytes shorter than choosing long, but the string can only be 2^15-1 Bytes long.Persian:
نقل قول:با تابع put میتونید در فایل بنویسید و با تابع get میتونید از فایل بخونید !
البته تو این روش یونیکد هم ساپورت میکنه به قول نویسنده کد
کد:
