XSupportsLocale(3)						  XLIB FUNCTIONS						XSupportsLocale(3)

NAME

       XSupportsLocale, XSetLocaleModifiers - determine locale support and configure locale modifiers

SYNTAX

       Bool XSupportsLocale(void);

       char *XSetLocaleModifiers(char *modifier_list);

ARGUMENTS

       modifier_list
		 Specifies the modifiers.

DESCRIPTION

       The XSupportsLocale function returns True if Xlib functions are capable of operating under the current locale.  If it returns False, Xlib
       locale-dependent functions for which the XLocaleNotSupported return status is defined will return XLocaleNotSupported.  Other Xlib locale-
       dependent routines will operate in the ``C'' locale.

       The XSetLocaleModifiers function sets the X modifiers for the current locale setting.  The modifier_list argument is a null-terminated
       string of the form ``{@category=value}'', that is, having zero or more concatenated ``@category=value'' entries, where category is a cate-
       gory name and value is the (possibly empty) setting for that category.  The values are encoded in the current locale.  Category names are
       restricted to the POSIX Portable Filename Character Set.

       The local host X locale modifiers announcer (on POSIX-compliant systems, the XMODIFIERS environment variable) is appended to the modi-
       fier_list to provide default values on the local host.  If a given category appears more than once in the list, the first setting in the
       list is used.  If a given category is not included in the full modifier list, the category is set to an implementation-dependent default
       for the current locale.	An empty value for a category explicitly specifies the implementation-dependent default.

       If the function is successful, it returns a pointer to a string.  The contents of the string are such that a subsequent call with that
       string (in the same locale) will restore the modifiers to the same settings.  If modifier_list is a NULL pointer, XSetLocaleModifiers also
       returns a pointer to such a string, and the current locale modifiers are not changed.

       If invalid values are given for one or more modifier categories supported by the locale, a NULL pointer is returned, and none of the cur-
       rent modifiers are changed.

       At program startup, the modifiers that are in effect are unspecified until the first successful call to set them.  Whenever the locale is
       changed, the modifiers that are in effect become unspecified until the next successful call to set them.  Clients should always call XSet-
       LocaleModifiers with a non-NULL modifier_list after setting the locale before they call any locale-dependent Xlib routine.

       The only standard modifier category currently defined is ``im'', which identifies the desired input method.  The values for input method
       are not standardized.  A single locale may use multiple input methods, switching input method under user control.  The modifier may specify
       the initial input method in effect or an ordered list of input methods.	Multiple input methods may be specified in a single im value
       string in an implementation-dependent manner.

       The returned modifiers string is owned by Xlib and should not be modified or freed by the client.  It may be freed by Xlib after the cur-
       rent locale or modifiers are changed.  Until freed, it will not be modified by Xlib.
