Apart from LC_MESSAGES, these variables affect a number of ANSI C functions. The following is from a draft of the C9X standard (although it's basically unchanged since C89). [#2] The setlocale function selects the appropriate portion of the program's locale as specified by the category and locale arguments. The setlocale function may be used to change or query the program's entire current locale or portions thereof. The value LC_ALL for category names the program's entire locale; the other values for category name only a portion of the program's locale. LC_COLLATE affects the behavior of the strcoll and strxfrm functions. LC_CTYPE affects the behavior of the character handling functions174) and the multibyte and wide-character functions. LC_MONETARY affects the monetary formatting information returned by the localeconv function. LC_NUMERIC affects the decimal-point character for the formatted input/output functions and the string conversion functions, as well as the nonmonetary formatting information returned by the localeconv function. LC_TIME affects the behavior of the strftime and strfxtime functions. LC_MESSAGES is used by gettext() etc to select a message catalogue. However, note that libc uses gettext() internally (e.g. for error messages), so it may affect programs which don't explicitly use gettext(). However: 1. Most of these variables only have an effect if the program calls setlocale() with an empty string as the second argument; otherwise, the program behaves as if the "C" (or "POSIX") locale was selected. Also, a program may use some variables while ignoring others; E.g. using LC_NUMERIC complicates matters if the program needs to write floating-point numbers to network streams or files which will be read by programs which assume that the decimal separator is a dot (aka period, full-stop). 2. If LC_ALL is set, it overrides the settings of all of the other LC_* variables. OTOH, the value of LANG is used as a default for any categories for which the appropriate LC_* variable is unset. More details may be available from the manual pages for the relevant functions, the "libc" Info file, and various standards documents. I have never heard of these. -- Glynn Clements <glynn.clements(a)virgin.net&gt;
