Try posting on the "windows programming" board.
Actually, I can tell you your problem:
> while( fwscanf(fptr,L"%C", &c)!= EOF)
What you're doing here is saying:
"compare the return value of "fscanf()" with "EOF"
This is not what you want.
Quzah.Code:do { fwscanf( fptr, L"%C", &c ) if( c != EOF ) wprintf(L"%C \n",c); } while( c != EOF );
Your code is wrong. Anyways I may post this on the Windows board but I'm trying to scan a file with special characters like in the question on this board.
How's it wrong? It's your code stuck into a 'do while' instead of a 'while'. The reason I suggested the windows board is because I'm unsure of the return values of those 'w' functions.
Quzah.
It returns EOF if it reads the 'end of file'. It does not store EOF in the variable. It is the same as fscanf which I have used many times so I know that the syntax is correct. The only difference is that it may return WEOF instead of EOF. But it still didn't run. I did post this on the windows programming board. So how does one scan a textfile for unicode characters (16 bit).

One byte at a time, with byte-by-byte comparisons. (Or, just
16 bits at a time, with 16bit numerical comparison.) (You just
can't expect to be able to use standard 'string' functions on
them.)
Quzah.
I think it scans 16 bits at a time. It can do comparisons but not standard C comparisons. It has it's own special functions for that. I just wanted to be able to scan that special character. Maybe unicode can only scan files that were created by the computer just like binary files. That could be a plausable explanation why it didn't work on the plain text file. It may need some special formatting.
Believe it or not there is a wcscmp() and a wcscpy(). Basically everything can be done. Cool.
is it there in C89 ? Is it there in C99 ? What header files have to be included ?
#include<wchar.h>
#include<wctype.h>
It's all over C9899. I have this document. This is pure ISO/IEC.
