25 @brief Introduction to the m17n library.
29 The API of the m17n library is divided into these four.
34 It provides basic modules to handle M-texts. They do not require
35 the m17n database. To use this API, an application program must
36 include <m17n-core<EM></EM>.h> and be linked by -lm17n-core.
40 It provides modules that utilize the m17n database (code
41 conversion, character property, etc). They load various kinds of
42 data from the database on demand. To use this API, an application
43 program must include <m17n<EM></EM>.h> and be linked by
46 When you use this API, CORE API is also available.
50 It provides GUI modules such as drawing and inputting M-texts on a
51 graphic device. The API itself is independent on a graphic device
52 but most functions require an argument MFrame which is created for
53 a specific type of graphic device. Currently, a null device, X
54 Window System, and an image date (gdImagePtr) of GD library are
55 supported as a graphic device.
57 On a frame of the null device, you can't draw text nor use an
58 input method (but, for instance, the function mdraw_glyph_list ()
61 On a frame of the X Window System, you can use the whole GUI API.
63 On a frame of GD library, you can use all drawing API but can't
66 To use this device, an application program must include
67 <m17n-gui<EM></EM>.h> and be linked by -lm17n-core -lm17n
70 When you use this API, CORE and SHELL API are also available.
74 It provides miscellaneous functions to support error handling and
75 debugging. This API cannot be used by itself, but with one or
76 more APIs listed above. To use the API, an application program
77 must include <m17n-misc<EM></EM>.h> in addition to one of a header
82 See also the section @ref m17n-config "m17n-config(1)".
84 <em>ENVIRONMENT VARIABLE</em>
86 The m17n library pays attention to these environment variables.
91 Name of a directory that contains data of the m17n database. See
92 @ref m17nDatabase for more details.
96 Environment variables whose name start by "MDEBUG_" controls
97 printing of debug information. See @ref m17nDebug for more
102 <em>API NAMING CONVENTION</em>
104 The library exports functions, variables, macros, and types. All
105 of them start by the letter 'm' or 'M' followed by an object name
106 (e.g. "symbol" and "plist", but "mtext" object is given the name
107 "text" to avoid double 'm' at the head) or a module name
112 <li> functions -- mobject () or mobject_xxx ()
114 They start with 'm' followed by lower case object name. For
115 example, msymbol (), mtext_ref_char (), mdraw_text ().
117 <li> non-symbol variables -- mobject, or mobject_xxx
119 The naming convention is the same as functions (e.g. mface_large).
121 <li> symbol variables -- Mname
123 Variables of type MSymbol start with 'M' followed by their names
124 (e.g. Mlanguage (name is "language"), Miso_2022 (name is
127 <li> macros -- MOBJECT_XXX
129 They start by 'M' followed by upper case object names.
131 <li> types -- MObject or MObjectXxx
133 They start by 'M' followed by capitalized object names (e.g.
134 MConverter, MInputDriver).

897 called with invalid arguments, it returns a value that indicates
898 error and at the same time sets the external variable #merror_code

901 The second type is memory allocation errors. When the required
