up

Converts all Unicode characters in the string that have a case to uppercase.

The exact manner that this is done depends on the current locale, and may result in the number of characters in the string increasing. ( For instance, the German ess-zet will be changed to SS.)

Example: Convert all lowercase ASCII letters to uppercase:

public static int main (string[] args) {
	// Output: ``YOU ADMIRE OUR TECHNOLOGY, HUMAN?``
	string up = "You admire our technology, human?".up ();
	print ("%s\n", up);
	return 0;
}

valac --pkg glib-2.0 string.up.vala

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, with all characters converted to uppercase.
