Thread: how can i read a unicode char from a file ?

when i save a file as Unicode every char will be 2-byte long

how can i read it from a file ??

if i use for example

Code:

FILE *fp;
c = getc(fp)

the c will contain a one byte ??
because i get it a character by character and long of the character just one byte !!!!!!!!!

i want to read the character so it will be 2 byte

cuz i want the program take the char as Unicode and convert it to something like ISO or Cp .. etc

use fread() then

is there another way other than fread() ??

there is an error when i use fread() , here`s the problem

Code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

int main(int argc,char *argv[])
{

	FILE *out;
	FILE *in;
	wchar_t *ch;

    if((ch=(wchar_t *)malloc(sizeof(wchar_t))) == NULL)
    {
        printf("Error: No enough memory\n");
        getchar();
        return 1;
    }
	in = fopen("test.txt","rb");
	out = fopen("output.txt","wb");
	if(in == NULL)
	{
		printf("Can`t open file:%s\n",argv[1]);
		exit(0);
	}

	while(fread(ch,sizeof(wchar_t),1,in) > 0)
	{
		printf("%d\n",ch);
		fwrite(ch,sizeof(wchar_t),1,out);
	}

	fclose(in);
	fclose(out);
	return 0;
}

test.txt include the char

Code:

ب

and if i read it and printf it using :

Code:

printf("%d\n",ch);

it output this number :
2824864
why ??

i am sure that the char

Code:

ب

in unicode equal to 1576

so the question is
how could i print out the unicode decimal value of a char in a unicode text file ?

Ops, sorry i found the problem ..

the problem is that i print out the address looooolz... i forget to do this
*ch

thanks zacs for help

There are wide equivalents of most things in C99.
