I don't see any reference to fdata in your code, unless it is defined
somewhere in the header files you include, something I haven't checked
into.
I've tried compiling your code anyway, and found the following:
First, the line that says
dfile=fopen("darg", "w");
has the compiler telling me that dfile is undefined. I'm guessing that
you wanted to write:
FILE *dfile=fopen("darg", "w");
in which case, you should have declared dfile at the top of your
function, following good c/c++ programming practices. Also, when using
fopen, it's a really good idea to check that your pointer is actually
assigned to a open file after you open it.
The next error gcc returns is 4 lines later, saying that dfile isn't a
const char*:
printf(dfile, usr);
I have no clue what you're trying to do here. If you meant to use
dfile as a pointer to an open file, I don't see why you'd want to
print it out to stdout.
I didn't try to fix this farther. Also, I'm wondering why you're
including c++ header files, as if you're fixing to write c++ code, but
then write your code entirely in c? If you're going to do that, then
you might as well include fstream, and use ifstream and ofstream for
file i/o, which in my humble opinion is a heck simpler then using
fopen.
