4.6.16 __LC_NUMERIC_DEF

This macro is used to create blocks used when formatting numbers. The definition from

rt_locale.h

and sample code are shown in Example 4-13.

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

Example 4-13 LC_NUMERIC_DEF

#define __LC_NUMERIC_DEF(sym,ln,dp,ts,gr) \

static const int sym##_index = ~3 & (3 + (sizeof(dp)+sizeof(ts)+sizeof(gr)+ \

20) + (~3 & (3 + sizeof(ln)))); \

static const char sym##_lname[~3 & (3 + sizeof(ln))] = ln; \

static const int sym##_pname = -4-(~3 & (3 + sizeof(ln))); \

static const int sym##_start = 12; \

static const int sym##_tsoff = (sizeof(dp)+12); \

static const int sym##_groff = (sizeof(dp)+sizeof(ts)+12); \

static const char sym##_dptxt[] = dp; \

static const char sym##_tstxt[] = ts; \

static const char sym##_grtxt[] = gr;

Usage

See _get_lc_numeric() on page 4-37. See also __LC_CTYPE_DEF on page 4-42 for

details of the side-effects of compiler optimizations.

4.6.17 __LC_MONETARY_DEF

This macro is used to create blocks used when formatting monetary values. The

definition from

rt_locale.h

and sample code are shown in Example 4-14.

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

Example 4-14 LC_MONETARY_DEF

#define __LC_MONETARY_DEF(sym,ln,ic,cs,md,mt,mg,ps,ns, \

id,fd,pc,pS,nc,nS,pp,np) \

static const int sym##_index = ~3 & (3 + (sizeof(ic)+sizeof(cs)+sizeof(md)+ \

sizeof(mt)+sizeof(mg)+sizeof(ps)+ \

sizeof(ns)+44) \
