XSupportsLocale, XSetLocaleModifiers \- determine locale support and configure locale modifiers

Bool XSupportsLocale\^(void);
|
|

|
|
char *XSetLocaleModifiers\^(\^char *\fImodifier_list\fP\^);

.SH ARGUMENTS
|
|
.IP \fImodifier_list\fP 1i
|
|
Specifies the modifiers.
|
|
.SH DESCRIPTION
|
|
The
|
|
.B XSupportsLocale
|
|
function returns
|
|
.B True
|
|
if Xlib functions are capable of operating under the current locale.
|
|
If it returns
|
|
.BR False ,
|
|
Xlib locale-dependent functions for which the
|
|
.B XLocaleNotSupported
|
|
return status is defined will return
|
|
.BR XLocaleNotSupported .
|
|
Other Xlib locale-dependent routines will operate in the \*(lqC\*(rq locale.
|
|
.LP
|
|
The
|
|
.B XSetLocaleModifiers
|
|
function sets the X modifiers for the current locale setting.
|
|
The modifier_list argument is a null-terminated string of the form
|
|
\*(lq{@\^\fIcategory\fP\^=\^\fIvalue\fP\^}\*(rq, that is,
|
|
having zero or more concatenated \*(lq@\^\fIcategory\fP\^=\^\fIvalue\fP\^\*(rq
|
|
entries, where \fIcategory\fP is a category name
|
|
and \fIvalue\fP 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.
|
|
.LP
|
|
The local host X locale modifiers announcer (on POSIX-compliant systems,
|
|
the XMODIFIERS environment variable) is appended to the modifier_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.
|
|
.LP
|
|
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,
|
|
.B XSetLocaleModifiers
|
|
also returns a pointer to such a string,
|
|
and the current locale modifiers are not changed.
|
|
.LP
|
|
If invalid values are given for one or more modifier categories supported by
|
|
the locale, a NULL pointer is returned, and none of the
|
|
current modifiers are changed.
|
|
.LP
|
|
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
|
|
.B XSetLocaleModifiers
|
|
with a non-NULL modifier_list after setting the locale
|
|
before they call any locale-dependent Xlib routine.
|
|
.LP
|
|
The only standard modifier category currently defined is \*(lqim\*(rq,
|
|
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.
|
|
.LP
|
|
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 current locale or modifiers are changed.
|
|
Until freed, it will not be modified by Xlib.
