Function

GLibascii_toupper

Declaration [src]

gchar
g_ascii_toupper (
  gchar c
)

Description [src]

Convert a character to ASCII upper case. If the character is not an ASCII lower case letter, it is returned unchanged.

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.

Parameters

c

Type: gchar

Any character.

Return value

Type: gchar

The result of the conversion.
