.SH NAME
minput_config_command - Configure the key sequence of an input method command. 


.SH SYNOPSIS
int
\fBminput_config_command\fP (\fBMSymbol\fP
\fIlanguage\fP, \fBMSymbol\fP
\fIname\fP, \fBMSymbol\fP
\fIcommand\fP, \fBMPlist\fP *
\fIkeyseqlist\fP)


.SH DESCRIPTION
The
.ft B
minput_config_command()
.ft R
function assigns a list of key sequences
.ft B
keyseqlist
.ft R
to the command
.ft B
command
.ft R
of the input method specified by
.ft B
language
.ft R
and
.ft B
name\fP.
.ft R
.PP
If
.ft B
keyseqlist
.ft R
is a non-empty plist, it must be a list of key sequences, and each key sequence must be a plist of symbols.
.PP
If
.ft B
keyseqlist
.ft R
is an empty plist, any configuration and customization of the command are cancelled, and default key sequences become effective.
.PP
If
.ft B
keyseqlist
.ft R
is NULL, the configuration of the command is canceled, and the original key sequences (what saved in per-user customization file, or the default one) become effective.
.PP
In the latter two cases,
.ft B
command
.ft R
can be
.ft B
Mnil
.ft R
to make all the commands 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 key assignment of a global command, not that of a specific input method.
.PP
The configuration takes effect for input methods opened or re-opened later in the current session. In order 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

.SH RETURN VALUE
.PP.RS 4
If the operation was successful, this function returns 0, otherwise returns -1. The operation fails in these cases: 
.PD 0

.IP "\(bu" 2

.SS keyseqlis is not in a valid form. 
.IP "\(bu" 2

.SS comman is not available for the input method. 
.IP "\(bu" 2

.SS language
.ft R
and
.ft B
nam do not specify an existing input method.
