Simple way to convert from a WCHAR to a string?

Hello. What's an easy way to convert from a WCHAR to a string? Thanks!

If you mean to convert a wchar_t string to a char string using standard C, then:

Code:

---

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

int main(void) {
    wchar_t wstr[100] = L"hello world";
    char str[50];
    wcstombs(str, wstr, 49);
    printf("%u: %s\n", strlen(str), str);
    return 0;
}

---

If you give more information about why you want to do this, there may be a better way. E.g., you may want to turn off unicode in MSVC++.
