C fwrite add new line

Personally, I would write the data you want at the beginning to a new file, then the data of the old file after it--delete the old then rename the new to the old file. But that may be a bit of a sloppy hack.

If you're creative I bet you can read a block of the file's data then over-write a portion of it with the data you want at the beginning, then continue reading and writing through until the eof to preserve the file's data, basically swapping a portion to memory.

But, on the other hand I don't usually work with files like that. I prefer to create the file in the correct order in one sweep but unfortunately I can't in this situation. I am dumping a undetermined amount of data from hardware to a file, this data can be upwards of a gigabyte; the amount of data I am going to capture is not know at the beginning.

I then have to insert a header into the beginning of the file that contains data describing the file with the length of the file and other fields that do not have set lengths so I can not just create a place holding space for the data to be overwritten in later.

What is the fastest file operation to dump content from one file to another, I am using fstream. Thanks again for all the help! It's fastest to call another program to do that for you:After this we can retrieve our exchange keys from the container. If the keys doesn’t exist I will create a brand new pair.

This code does exactly this.

From PHP you are able to open up a file on your server and write to it. If the file does not exist we can create it, however, if the file already exists you must chmod it to so it will be writable.

When writing to a file, the first thing you need to do is to open up the file.
