Answer 1

Here are two functions that can be used: mbstowcs_s and wcstombs_s.

mbstowcs_s: Converts a sequence of multibyte characters to a corresponding sequence of wide characters. wcstombs_s: Converts a sequence of wide characters to a corresponding sequence of multibyte characters.

errno_t wcstombs_s(
   size_t *pReturnValue,
   char *mbstr,
   size_t sizeInBytes,
   const wchar_t *wcstr,
   size_t count 
);

errno_t mbstowcs_s(
   size_t *pReturnValue,
   wchar_t *wcstr,
   size_t sizeInWords,
   const char *mbstr,
   size_t count 

);
