NAME

       minput_get_variable - Get information about input method variable(s).

SYNOPSIS

       MPlist* minput_get_variable (MSymbol language, MSymbol name, MSymbol variable)

DESCRIPTION

       Get information about input method variable(s). The minput_get_variable() function returns information
       about variable variable of the input method specified by language and name.  An input method variable
       controls behavior of an input method.

       There are two kinds of variables, global and local. A global variable has a global definition, and the
       description and the value may be inherited by a local variable. Each input method defines a local
       variable which has local value. It may also declare a local variable that inherits definition of a global
       variable of the same name.

       If language is Mt and name is Mnil, information about a global variable is returned. Otherwise
       information about a local variable is returned.

       If variable is Mnil, information about all variables is returned.

       The return value is a well-formed plist (Property List) of this format:

         ((NAME DESCRIPTION STATUS VALUE [VALID-VALUE ...]) ...)

       NAME is a symbol representing the variable name.

       DESCRIPTION is an M-text describing the variable, or Mnil if the variable has no description.

       STATUS is a symbol representing how the value is decided. The value is Mnil (the default value),
       Mcustomized (the value is customized by per-user customization file), or Mconfigured (the value is set by
       the call of minput_config_variable()). For a local variable only, it may also be Minherited (the value is
       inherited from the corresponding global variable).

       VALUE is the initial value of the variable. If the key of this element is Mt, the variable has no initial
       value. Otherwise, the key is Minteger, Msymbol, or Mtext and the value is of the corresponding type.

       VALID-VALUEs (if any) specify which values the variable can have. They have the same type (i.e. having
       the same key) as VALUE except for the case that VALUE is an integer. In that case, VALID-VALUE may be a
       plist of two integers specifying the range of possible values.

       If there no VALID-VALUE, the variable can have any value as long as the type is the same as VALUE.

       If variable is not Mnil, the first element of the returned plist contains the information about variable.

RETURN VALUE

       If the requested information was found, a pointer to a non-empty plist is returned. As the plist is kept
       in the library, the caller must not modify nor free it.

       Otherwise (the specified input method or the specified variable does not exist), NULL is returned.
