In C language, what is the translation of mbtowc function?

C library function int mbtowc(whcar_t *pwc, const char *str, size_t n)Convert a multi-byte sequence to wide characters.

The following is the declaration of the mbtowc() function.

int mbtowc(whcar_t *pwc, const char *str, size_t n)

The parameters are as follows:

• pwc − This is a pointer to a wchar_t type object.

• #str − This is a pointer to the first byte of a multibyte character.

• #str − This is a pointer to the first byte of a multibyte character.

• #n − This is the maximum number of bytes to check for character length.

The return value is as follows:

• If str is not NULL, the mbtowc() function returns the number of bytes consumed starting from str. If Returns 0 if s points to a null byte, or -1 on failure.

• If str is NULL, the mbtowc() function returns a non-zero value, indicating that the encoding has a non-trivial shift state, or zero if the encoding is stateless.

Example

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main () {
   char *str = "This is tutorialspoint.com";
   wchar_t mb[100];
   int len;
   len = mblen(NULL, MB_CUR_MAX);
   mbtowc(mb, str, len*strlen(str) );
   wprintf(L"%ls </p><p>", mb );
   return(0);
}

Output
