GRAPHEME_IS_TITLECASE(3) - Library Functions Manual
NAME
grapheme_is_titlecase - check if codepoint array is titlecase
SYNOPSIS
#include <grapheme.h>
size_t
grapheme_is_titlecase(const uint_least32_t *str, size_t len, size_t *caselen);
DESCRIPTION
The
grapheme_is_titlecase()
function checks if the codepoint array
str
is titlecase and writes the length of the matching titlecase-sequence to the integer pointed to by
caselen,
unless
caselen
is set to
NULL
.
If
len
is set to
SIZE_MAX
(stdint.h is already included by grapheme.h) the codepoint array
src
is interpreted to be NUL-terminated and processing stops when a
NUL-byte is encountered.
For UTF-8-encoded input data grapheme_is_titlecase_utf8(3) can be used instead.
RETURN VALUES
The
grapheme_is_titlecase()
function returns
true
if the codepoint array
str
is titlecase, otherwise
false
.
SEE ALSO
grapheme_is_titlecase_utf8(3), libgrapheme(7)

grapheme_is_titlecase() is compliant with the Unicode 15.0.0 specification.
