14 nl_item, shall be defined as described in <nl_types.h> .

17 indicate in which setlocale() category each item is defined.

91 value, '+' if the symbol should appear
92 after the value, or '.' if the symbol
93 should replace the radix character. If
94 the local currency symbol is the empty
95 string, implementations may return the
96 empty string ( "" ).
97 If the locale's values for p_cs_precedes and n_cs_precedes do not
99 match, the value of nl_langinfo(CRNCYSTR) is unspecified.
100 The following shall be declared as a function and may also be defined
102 as a macro. A function prototype shall be provided.
103 char *nl_langinfo(nl_item);
106 Inclusion of the <langinfo.h> header may also make visible all symbols
108 from <nl_types.h>.
109 The following sections are informative.
111
113 Wherever possible, users are advised to use functions compatible with
114 those in the ISO C standard to access items of langinfo data. In par‐
115 ticular, the strftime() function should be used to access date and time
116 information defined in category LC_TIME. The localeconv() function
117 should be used to access information corresponding to RADIXCHAR,
118 THOUSEP, and CRNCYSTR.
