#include <wchar.h>
#include <stdio.h>
#include <stdlib.h>
#define _TEXT(x) L ## x
int main() {

FILE *fp = NULL;
wchar_t *filename = _TEXT("oov.txt" );
wchar_t *p = _TEXT("hello ");

wprintf(_TEXT(" %S\n"), p);

wprintf(_TEXT(" %d \n"), wcslen(p));

fp = fopen( "oov.txt", "w");
fwprintf(fp, _TEXT("%S"), p);
return 0;

Hi, all: I just need to parse a unicode file, and assume to get data one line by one line. I use _wfopen(), fgetws(), wcslen(), wcsstr(), making it work normally on Windows platform. However, when migrate it to Linux platform, issue occurs. Linux only has fopen() function, and fgetws() could not correctly get lines, in fact, it gets nothing.
