size_t- Described at the start of this chapter.
div_t- This is the type of the structure returned by
div. ldiv_t- This is the type of the structure returned by
ldiv. NULL- Again, described at the start of this chapter.
EXIT_FAILUREEXIT_SUCCESS- These may be used as arguments to
exit. MB_CUR_MAX- The maximum number of bytes in a multibyte character from the extended character set specified by the current locale.
