collate_key

Description:

[ CCode ( cname = "g_utf8_collate_key" ) ]
public string collate_key (ssize_t len = -1)

Converts a string into a collation key that can be compared with other collation keys produced by the same function using strcmp.

The results of comparing the collation keys of two strings with strcmp will always be the same as comparing the two original keys with collate.

Note that this function depends on the [current locale](running.html#locale).

Note that the returned string is not guaranteed to be in any encoding, especially UTF-8. The returned value is meant to be used only for comparisons.

Parameters:

len	length of `str`, in bytes, or -1 if `str` is nul-terminated.
str	a UTF-8 encoded string.

Returns:

a newly allocated string. The contents of the string are only meant to be used when sorting. This string should be freed with g_free when you are done with it.
