this ensures that all writes with fwrite() are completed before other processes are allowed to write to that output stream.
to zajišťuje, že všechny zápisy jsou dokončeny dřív, než ostatní procesy mohou do souboru zapisovat.

this means that if there are two processes wanting to write to the same output stream (a file), each is paused after 8k of data to allow the other to write. set_file_buffer() sets the buffering for write operations on the given filepointer fp to buffer bytes.
funkce set_file_buffer() nastavuje buffering pro zápis přes daný deskriptor fp na buffer bytů.
