Thread: Function to write two bytes at a time to a file?

I've also tried fputs, but that only works for strings; the values are stored as integers in this case.

Any tips for injecting these double-byte values into a file? Help is much appreciated!

Look at fprintf() in your library documentation...

If you have the 2 byte value in a short int you can easily print it to the file as decimal, hex, or octal.
If it's in a string you can just print it directly to the file.

Really... this isn't hard.
