Function

GLibascii_tolower

Declaration

gchar
g_ascii_tolower (
  gchar c
)

Description

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

Unlike the standard C library tolower() function, this only recognizes standard ASCII letters and ignores the locale, returning all non-ASCII characters unchanged, even if they are lower 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.
