4.6.15 __LC_TIME_DEF

This macro is used to create blocks used when formatting time or date values. The

definition from

rt_locale.h

and sample code are shown in Example 4-12.

For all the macros, the first two arguments are a symbol prefix and a locale name. The

resulting locale block is addressed by the expression

&symprefix_start

, and the index

entry by the expression

&symprefix_index
