ascii_toupper].

Parameters:

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

Returns:

a newly-allocated string, with all the lower case characters in str converted to upper case. (Note that this is unlike the old [func@GLib.strup], which modified the string in place.)
