Inserting

are there any open/write functions for C , which do not overwrite chars in a file , but insert them ?

or do i have to write a shitty loop that just reads , stores and writes a char ?

also discuss file and string handling libraries because most that i have seen suck .

This is how a lot of simple text editors work, and since even the early days of computing, CPUs can move the entire contents of main memory forward one byte in a few ms, it's not surprising that this method has remained quite standard.
