wcslen -- Calculate Length of Wide-Character String

Format

#include <wcstr.h>
size_t wcslen(const wchar_t *string);

Language Level: XPG4
wcslen computes the number of wide characters in the string pointed to by string.

Return Value
wcslen returns the number of wide characters in string, excluding the terminating wchar_t null character.

Example
This example computes the length of the wide-character string string.

#include <stdio.h>
#include <wcstr.h>
int main(void)
{
  wchar_t * string = L"abcdef";
  printf( "Length of \"%ls\" is %i\n", string, wcslen( string ));
  return 0;
  /**************************************************************
     The output should be:
     Length of "abcdef" is 6
  **************************************************************/
}
