Declaration [src]

g_ascii_toupper (
  gchar c

Description [src]

Convert a character to ASCII upper case.

Unlike the standard C library toupper() function, this only recognizes standard ASCII letters and ignores the locale, returning all non-ASCII characters unchanged, even if they are upper case letters in a particular character set. Also unlike the standard library function, this takes and returns a char, not an int, so don’t call it on EOF but no need to worry about casting to #guchar before passing a possibly non-ASCII character in.


c gchar

Any character.

Return value

Returns: gchar

The result of converting c to upper case. If c is not an ASCII lower case letter, c is returned unchanged.
