It depends on the type of file and how you're reading it.
Assuming you're reading a text file:
int main()
{
char buf[1024];
FILE *fptr;
fptr = fopen( "file.txt", "rt" );
if( fptr == NULL )
{
// file didnt open, so exit
printf( "Unable to open file.\n" );
exit(1);
}
buf = fgets( buf, 1024, fptr );
while( buf != NULL )
{
// do something with that 1024 byte block, eg print it
printf( "%s", buf );
buf = fgets( buf, 1024, fptr );
}
return 0;
}
That should do quite nicely, providing i havent made any mistakes :)

Subject: Re: [hlcoders] file reading from...
when using c++ file streams to detect end of file you can do something like
ifstream if;
if.open("filename", flags);
while(!in.eof() )
{
read lots of stuff in
}
in.close();
i am not fluent with c's file openings and such but i have managed to open
files read from it etc but what i now require is how to check using c style
syntax whether its at end of file or not?
So basically what is the c style end of file check i can use in my while and
if loops??? botman anyman :) ???
thanks peoples.
