NAME
unicode_grapheme_break, unicode_grapheme_break_init, unicode_grapheme_break_next, unicode_grapheme_break_deinit - unicode grapheme cluster boundary rules
SYNOPSIS
#include <courier-unicode.h>
|
unicode_grapheme_break_info_t unicode_grapheme_break_init(void); |
||
|
int unicode_grapheme_next(unicode_grapheme_break_info_t handle , char32_t c ); |
||
|
void unicode_grapheme_deinit(unicode_grapheme_break_info_t handle ); |
||
|
int unicode_grapheme_break(char32_t a , char32_t b ); |
DESCRIPTION
These functions implement the unicode grapheme cluster breaking algorithm. Invoke unicode_grapheme_break_init () to initialize the grapheme cluster breaking algorithm. unicode_grapheme_break_init () returns an opaque handle. Each subsequent call to unicode_grapheme_break_next () passes this handle, and the next character. unicode_grapheme_break_next () returns a non-0 value if there's a grapheme break before the character, in a sequence of Unicode characters. unicode_grapheme_break_deinit () releases all resources used by the grapheme breaking handle, and the unicode_grapheme_break_info_t handle is no longer valid after this call.
The first call to unicode_grapheme_break_next () always returns non-0, as per the GB1 rule.
unicode_grapheme_break
()
is a simplified interface that returns non-zero if there is
a grapheme break between two unicode characters
a
and
b
. This is is equivalent to calling
unicode_grapheme_break_init
(), followed by two calls
to
unicode_grapheme_break_next
(), and finally
unicode_grapheme_break_deinit
(), then returning the
result of the second call to
unicode_grapheme_break_next
().
