The __LC_COLLATE_TRIVIAL_DEF macro defines an array that has the element value equal
to its index number.
__LC_COLLATE_TRIVIAL_DEF(lccoll_c, "C") is equivalent to the code
in Example 4-5.
Example 4-5 LC_COLLATE_DEF
__LC_COLLATE_DEF(lccoll_c, "C")
{
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f,
...
0xf0, 0xf1, 0xf2, 0xf3, 0xf4, 0xf5, 0xf6, 0xf7,
0xf8, 0xf9, 0xfa, 0xfb, 0xfc, 0xfd, 0xfe, 0xff
};
4.6.6 _get_lc_monetary()
_get_lc_monetary() must return a pointer to an __lc_monetary_blk structure. Use the
macros in Example 4-6 on page 4-36 to create the structure.
