NAME

grapheme_is_lowercase_utf8 - check if UTF-8-encoded string is lowercase  

SYNOPSIS

In grapheme.h Ft size_t Fn grapheme_is_lowercase_utf8 const char *str size_t len size_t *caselen  

DESCRIPTION

The Fn grapheme_is_lowercase_utf8 function checks if the UTF-8-encoded string str is lowercase and writes the length of the matching lowercase-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 UTF-8-encoded string src is interpreted to be NUL-terminated and processing stops when a NUL-byte is encountered.

For non-UTF-8 input data grapheme_is_lowercase3 can be used instead.  

RETURN VALUES

The Fn grapheme_is_lowercase_utf8 function returns true if the UTF-8-encoded string str is lowercase, otherwise false  

SEE ALSO

grapheme_is_lowercase3, libgrapheme(7)  

STANDARDS

Fn grapheme_is_lowercase_utf8 is compliant with the Unicode 15.0.0 specification.
