How do I open a file in such a way that if the file doesn't exist it will be created and opened automatically?

Here's how I open a file for writing+ :
if( fopen_s( &f, fileName, "w+" ) !=0 ) {
printf("Open file failed\n");
return;
}
fprintf_s(f, "content");
If the file doesn't exist the open operation fails. What's the right way to fopen if I want to create the file automatically if the file doesn't already exist?
EDIT: If the file does exist, I would like fprintf to overwrite the file, not to append to it.
