Description

Details

enca_charset_has_ucs2_map ()

int         enca_charset_has_ucs2_map       (int charset);

Find whether we have charset -> UCS-2 map.

charset : An 8bit charset.
Returns : Nonzero when the map is available, zero otherwise.


enca_charset_ucs2_map ()

int         enca_charset_ucs2_map           (int charset,
                                             unsigned int *buffer);

Creates map from an 8bit charset to UCS-2.

The buffer must be at least 256*sizeof(unsigned int) long to hold the map.

charset : An 8bit charset.
buffer : Buffer to store the map to.
Returns : Nonzero when the map was successfully created, zero otherwise.


enca_number_of_charsets ()

size_t      enca_number_of_charsets         (void);

Returns number of known charsets.

Charsets idetifiers are assigned successively starting from zero, so last charset has identifier enca_number_of_charsets() - 1.

Returns : The number of charsets.


enca_analyser_langage ()

const char* enca_analyser_langage           (EncaAnalyser analyser);

Returns name of language which was analyser initialized for.

The returned string must be considered constant and must NOT be freed.

analyser : An analyser.
Returns : The language name.


enca_get_languages ()

const char** enca_get_languages             (size_t *n);

Returns list of known languages.

The returned strings are two-letter ISO-639 language codes, the same as enca_analyser_alloc() accepts.

The list of languages has to be freed by caller; the strings themselves must be considered constant and must NOT be freed.

n : The number of languages will be stored here.
Returns : The list of languages, storing their number into *n.


enca_get_language_charsets ()

int*        enca_get_language_charsets      (const char *langname,
                                             size_t *n);

Returns list of identifiers of charsets supported for language language.

The list of charset identifiers has to be freed by caller.

langname : Two-letter ISO-639 language code.
n : The number of charsets will be stored here.
Returns : The list of charsets, storing their number into *n. When language contains no charsets or langname is invalid, NULL is returned and zero stored into *n.
