Everytime when I want to insert data in a file I used write_file( , , -1) or fopen( , "a") to save data in files, if the order of lines doesn't matters. If the ordering does matter I used to save each line (format) in a buffer than I could handle it. Today I'm working on a new ranking system, and I need to know how to insert data between specified lines (if input kills higher than stored kills). I know I could do that with storing into a buffer, but I need to reopen the file with write option. With that way I need to use 2 whiles and it has a big working time (if has 5000+ lines), also I need to close than reopen the same file. I think is existing a better way that how I proceed.

In brief, how to edit a file?

IIRC, there is no "simple" method to insert a line. You would need to move every line below the spot you want to insert down one place. This means you need to read every line below the line of interest and re-write it. An SQL or SQL-like system would be much better for this.
