.SH NAME
minput_config_variable \- Configure the value of an input method variable. 


.SH SYNOPSIS
int
\fBminput_config_variable\fP (\fBMSymbol\fP
\fIlanguage\fP, \fBMSymbol\fP
\fIname\fP, \fBMSymbol\fP
\fIvariable\fP, \fBMPlist\fP *
\fIvalue\fP)


.SH DESCRIPTION
Configure the value of an input method variable. The
.ft B
minput_config_variable()
.ft R
function assigns
.ft B
value
.ft R
to the variable
.ft B
variable
.ft R
of the input method specified by
.ft B
language
.ft R
and
.ft B
name\fP.
.ft R
.PP
If
.ft B
value
.ft R
is a non\-empty plist, it must be a plist of one element whose key is
.ft B
Minteger\fP,
.ft R
.ft B
Msymbol\fP,
.ft R
or
.ft B
Mtext\fP,
.ft R
and the value is of the corresponding type. That value is assigned to the variable.
.PP
If
.ft B
value
.ft R
is an empty plist, any configuration and customization of the variable are canceled, and the default value is assigned to the variable.
.PP
If
.ft B
value
.ft R
is NULL, the configuration of the variable is canceled, and the original value (what saved in per\-user customization file, or the default value) is assigned to the variable.
.PP
In the latter two cases,
.ft B
variable
.ft R
can be
.ft B
Mnil
.ft R
to make all the variables of the input method the target of the operation.
.PP
If
.ft B
name
.ft R
is
.ft B
Mnil\fP,
.ft R
this function configures the value of global variable, not that of a specific input method.
.PP
The configuration takes effect for input methods opened or re\-opened later in the current session. To make the configuration take effect for the future session, it must be saved in a per\-user customization file by the function
.ft B
minput_save_config()\fP.
.ft R

If the operation was successful, this function returns 0, otherwise returns \-1. The operation fails in these cases: 
.PD 0

.IP "\(bu" 2
\fBvalue
.ft R
is not in a valid form, the type does not match the definition, or the value is our of range. 
.IP "\(bu" 2
\fBvariable
.ft R
is not available for the input method. 
.IP "\(bu" 2
\fBlanguage
.ft R
and
