24 /* The LC_MESSAGES locale category is the category used by the functions
25 gettext() and dgettext(). It is specified in POSIX, but not in ANSI C.
26 On systems that don't define it, use an arbitrary value instead.
27 On Solaris, <locale.h> defines __LOCALE_H (or _LOCALE_H in Solaris 2.5)
28 then includes <libintl.h> (i.e. this file!) and then only defines
29 LC_MESSAGES. To avoid a redefinition warning, don't define LC_MESSAGES
31 #if !defined LC_MESSAGES && !(defined __LOCALE_H || (defined _LOCALE_H && defined __sun))

36 implementation of gettext. */

44 /* Resolve a platform specific conflict on DJGPP. GNU gettext takes
45 precedence over _conio_gettext. */
55 /* We redirect the functions to those prefixed with "libintl_". This is
56 necessary, because some systems define gettext/textdomain/... in the C
57 library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer).
58 If we used the unprefixed names, there would be cases where the
59 definition in the C library would override the one in the libintl.so
60 shared library. Recall that on ELF systems, the symbols are looked
61 up in the following order:
63 2. in the shared libraries specified on the link command line, in order,
64 3. in the dependencies of the shared libraries specified on the link
66 4. in the dlopen()ed shared libraries, in the order in which they were
68 The definition in the C library would override the one in libintl.so if
70 * -lc is given on the link command line and -lintl isn't, or
71 * -lc is given on the link command line before -lintl, or
72 * libintl.so is a dependency of a dlopen()ed shared library but not
73 linked to the executable at link time.
74 Since Solaris gettext() behaves differently than GNU gettext(), this
75 would be unacceptable.
77 The redirection happens by default through macros in C, so that &gettext
78 is independent of the compilation unit, but through inline functions in
79 C++, in order not to interfere with the name mangling of class fields or
80 class methods called 'gettext'. */
