|o||If TAG0 is Mchar_table, the data is of the chartable type and provides information about each character. In this case, TAG1 specifies the type of the information and must be Msymbol, Minteger, Mstring, Mtext, or Mplist. TAG2 and TAG3 can be any symbols.|
|o||If TAG0 is Mcharset, the data is of the charset type and provides a decode/encode mapping table for a charset. In this case, TAG1 must be a symbol representing a charset. TAG2 and TAG3 can be any symbols.|
|o||If TAG0 is neither Mchar_table nor Mcharset, the data is of the plist type. See the documentation of the mdatabase_load() function for the details. In this case, TAG1, TAG2, and TAG3 can be any symbols.|
Application programs first calls the mdatabase_find() function to get a pointer to an object of the type MDatabase. That object holds information about the specified data. When it is successfully returned, the mdatabase_load() function loads the data. The implementation of the structure MDatabase is concealed from application programs.
Type of database.
The type MDatabase is for a database object. Its internal structure is concealed from an application program.
Directory for application specific data.
If an application program wants to provide a data specific to the program or a data overriding what supplied by the m17n database, it must set this variable to a name of directory that contains the data files before it calls the macro M17N_INIT(). The directory may contain a file mdb.dir which contains a list of data definitions in the format described in mdbDir(5).
The default value is NULL.
