GLibascii_strdown

gchar*
g_ascii_strdown (
  const gchar* str,
  gssize len
)

Converts all upper case ASCII letters to lower case ASCII letters.

`str`	`const gchar*`
	A string.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`len`	`gssize`
	Length of `str` in bytes, or -1 if `str` is nul-terminated.

Returns:	`gchar*`
	A newly-allocated string, with all the upper case characters in `str` converted to lower case, with semantics that exactly match g_ascii_tolower(). (Note that this is unlike the old g_strdown(), which modified the string in place.)
	The caller of the function takes ownership of the data, and is responsible for freeing it.
	The value is a NUL terminated UTF-8 string.
