## 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 to stderr.

- •

  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.

- •

  MDEBUG\_OUTPUT\_FILE -- If set to a file name, the above debugging information is appended to the file. If set to 'stdout', the information is printed to stdout.

- •

  Functions to print various objects in a human readable way. See the documentation of mdebug\_dump\_XXXX() functions.
