4 | The tolower function converts an uppercase letter to a corresponding\r | |
5 | lowercase letter. If the argument is a character for which isupper\r | |
6 | is true and there are one or more corresponding characters, as\r | |
7 | specified by the current locale, for which islower is true, the tolower\r | |
8 | function returns one of the corresponding characters (always the same one\r | |
9 | for any given locale); otherwise, the argument is returned unchanged.\r | |
10 | \r | |
11 | The toupper function converts a lowercase letter to a corresponding\r | |
12 | uppercase letter. If the argument is a character for which islower is true\r | |
13 | and there are one or more corresponding characters, as specified by the\r | |
14 | current locale, for which isupper is true, the toupper function returns one\r | |
15 | of the corresponding characters (always the same one for any given locale);\r | |
16 | otherwise, the argument is returned unchanged.\r | |
