.SH SYNOPSIS
void*
\fBmdatabase_load\fP (\fBMDatabase\fP *
\fImdb\fP)
.SH DESCRIPTION
Load a data from the database. The
.ft B
mdatabase_load()
.ft R
function loads a data specified in
.ft B
mdb
.ft R
and returns the contents. The type of contents depends on the type of the data.
.PP
If the data is of the
.ft I
plist
.ft R
.ft I
type\fP,
.ft R
this function returns a pointer to
.ft I
plist\fP.
.ft R
.PP
If the database is of the
.ft I
chartable
.ft R
.ft I
type\fP,
.ft R
it returns a chartable. The default value of the chartable is set according to the second tag of the data as below:
.PP
.PD 0
.IP "\(bu" 2
If the tag is
.ft B
Msymbol\fP,
.ft R
the default value is
.ft B
Mnil\fP.
.ft R
.IP "\(bu" 2
If the tag is

charset
.ft R
.ft I
type\fP,
.ft R
it returns a plist of length 2 (keys are both
.ft B
Mt\fP). The value of the first element is an array of integers that maps code points to the corresponding character codes. The value of the second element is a chartable of integers that does the reverse mapping. The charset must be defined in advance.
