The following data types are defined through
typedef:
div_t structure type returned by the
div() function
ldiv_t structure type returned by the
ldiv() function
lldiv_t structure type returned by the
lldiv() function
size_t as described in <
stddef.h>
wchar_t as described in <
stddef.h>
See
div(3C), which covers
div(),
ldiv(), and
lldiv(), and
stddef.h(3HEAD).
