NAME¶
rulexdb_search - search rulex database for specified word
SYNOPSIS¶
#include <rulexdb.h> int rulexdb_search(RULEXDB *rulexdb, const char *key, char *value, int flags);
DESCRIPTION¶
The rulexdb_search() function searches the database
referenced by rulexdb argument and tries to guess pronunciation for
the word specified by string pointed by key argument according to the
acquired info. The resulting string is
placed into the buffer pointed by value argument. This buffer must
have enough space for it. When no useful
info is found, the original word is copied to the value buffer and
RULEXDB_SPECIAL code is returned.
At first search is performed in the Explicit dictionary. If
it
succeeds, the result is returned and procedure exits
successfully. Otherwise the word is treated as an implicit form and
program tries to guess its base and find it in the Implicit
dictionary. If this process succeeds, the pronunciation string is
constructed according to the acquired data and procedure exits
successfully. At last, the word is matched against general rules. If
no match succeeds, then program exits with RULEXDB_SPECIAL code,
returning the original word as a result.
If this process appears to be not fully unsuccessful and some information was found in the database, then the resulting string is matched against correction rules and the first matched one is applied if any.
The last argument specifies which steps of the described process are to be performed. It consists of the following flags which may be bitwise-or'd to form wanted search mode:
- RULEXDB_EXCEPTIONS
- Search the word in the exceptions dictionary.
- RULEXDB_FORMS
- Try to treat specified word as an implicit form.
- RULEXDB_RULES
- Try to apply general rules.
- Zero value (no flags) means that full search (all stages) should be
- performed.
RETURN VALUE¶
The rulexdb_search() function returns RULEXDB_SUCCESS which is zero upon success, positive value RULEXDB_SPECIAL when specified word was not found, or negative error code if something is wrong.
ERRORS¶
- RULEXDB_FAILURE
- Referenced database has not been opened, internal data structures are corrupted or some other general failure has occurred.
- RULEXDB_EMALLOC
- Internal memory allocation error.
- RULEXDB_EINVKEY
- Invalid key specified.
- RULEXDB_EPARM
- Invalid parameters are specified.
