NAME
DICLib_intro - dictionary access library introduction

DESCRIPTION
The dictionary access library provides basic functions for kana-kanji conversion. The following files are prerequisite to using the dictionary access library:

Header file
    canna/RK.h
    An include file that contains data and function declarations for use by the kana-kanji conversion library. Include this file at compile time.

Libraries
    libcanna.a, libcanna.so
    Kana-kanji conversion libraries. Specify "-lcanna" at link time.

SUMMARY
The dictionary access library provides three major categories of functions:

¡¦  Code conversion functions

    Convert character string codes between double-width and single-width characters and between hiragana and katakana. External data and initialization procedures are not required.

¡¦  Romaji-kana conversion functions

    Convert Romaji to kana by using a Romaji-kana conversion table that defines the correspondence between Romaji and kana. The rules of Romaji-kana conversion can be altered by making modifications to this table.

¡¦  Kana-kanji conversion functions

    Convert kana to kanji through continuous clause conversion by using a kana-kanji conversion dictionary that defines the correspondence between readings and words. Kana-kanji conversion can be performed to meet specific applications by making modifications to this dictionary.

Among all the functions of Japanese input processing, this library performs only data conversion. To be able to enter Japanese text from a keyboard, therefore, it is necessary for users to write a keyboard handling routine within the application program.
