Detailed Description

Support for m17n library users to debug their programs.

The m17n library provides the following facilities to support the library users to debug their programs.

•: Environment variables to control printing of various information.

•: MDEBUG_INIT -- If set to 1, print information about the library initialization on the call of M17N_INIT().
•: MDEBUG_FINI -- If set to 1, print counts of objects that are not yet freed on the call of M17N_FINI().
•: MDEBUG_CHARSET -- If set to 1, print information about charsets being loaded from the m17n database.
•: MDEBUG_CODING -- If set to 1, print information about coding systems being loaded from the m17n database.
•: MDEBUG_DATABASE -- If set to 1, print information about data being loaded from the m17n database.
•: MDEBUG_FONT -- If set to 1, print information about fonts being selected and opened.
•: MDEBUG_FLT -- If set to 1, 2, or 3, print information about which command of Font Layout Table are being executed. The bigger number prints the more detailed information.
•: MDEBUG_INPUT -- If set to 1, print information about how an input method is running.
•: MDEBUG_ALL -- Setting this variable to 1 is equivalent to setting all the above variables to 1.
