   Non-standard (i.e. non-ISO C) functions.
       #define RANDOM_MAX   0x7FFFFFFF
       char * itoa (int val, char *s, int radix)
       char * ltoa (long val, char *s, int radix)
       char * utoa (unsigned int val, char *s, int radix)
       char * ultoa (unsigned long val, char *s, int radix)
       long random (void)
       void srandom (unsigned long __seed)
       long random_r (unsigned long *__ctx)

   Conversion functions for double arguments.
       Note that these functions are not located in the default library, libc.a, but in the
       mathematical library, libm.a. So when linking the application, the -lm option needs to be
       specified.
       #define DTOSTR_ALWAYS_SIGN   0x01        /* put '+' or ' ' for positives */
       #define DTOSTR_PLUS_SIGN   0x02        /* put '+' rather than ' ' */
       #define DTOSTR_UPPERCASE   0x04        /* put 'E' rather 'e' */
       #define EXIT_SUCCESS   0
       #define EXIT_FAILURE   1
