int | fflush (FILE *stream)
| Flush a stream. More...
int | sprintf (char *s, const char *fmt,...)
| format and string and save it to `s'. More...
int | printf_s (const char *_restrict_ fmt,...)
| format and print string. More...
int | vsprintf_s (char *_restrict_ s, rsize_t n, const char *_restrict_ format, va_list arg)

int | sprintf_s (char *_restrict_ s, rsize_t n, const char *_restrict_ format,...)
| format string and save it to `s'. More...
int | snprintf_s (char *_restrict_ s, rsize_t n, const char *_restrict_ format,...)
| Format string and save it to `s'. More...
int | sscanf_s (const char *_restrict_ s, const char *_restrict_ format,...)
