Rewrite a open file?

[philipwayne]

Is there a way to rewrite a open file in C? So say every time I want to rewrite to a file rather then having to reopen it I can just rewrite the contents inside. Any help is greatly appreciated.

As long as the file was opened for writing in the first place all you have to do is "seek" to the beginning of the file again.

Check your library documentation for seek.
