Detailed Description

UTF8 wrapper functions.

Function Documentation

normalize()

char * normalize ( const char * str, size_t len, size_t * newlen, utf8proc_option_t flags )

static

Normalizes a string

Parameters

str	String to normalize
len	String length
newlen	Pointer to size_t for the new string length
flags	Normalization flags

Returns

Newly allocated char, caller must free it.

utf8_wrap_casecmp()

int utf8_wrap_casecmp	(	const char *	str1,
		size_t	str1_len,
		const char *	str2,
		size_t	str2_len )

Compares two strings case insensitive. Set's errno to EINVAL if one string is invalid utf8.

Parameters

str1	String1
str1_len	String1 length
str2	String2
str2_len	String2 length

Returns

Same as strcasecmp

utf8_wrap_casefold()

char * utf8_wrap_casefold	(	const char *	str,
		size_t	len,
		size_t *	newlen )

Casefolds a string

Parameters

str	String to normalize
len	String length
newlen	Pointer to size_t for the new string length

Returns

Newly allocated char, caller must free it.

utf8_wrap_validate()

bool utf8_wrap_validate	(	const char *	str,
		size_t	str_len )

Checks if string is valid utf8

Parameters

str	String to validate
str_len	String length

Returns

true if string is valid, else false
