Function Macro

GLibascii_isupper

Declaration

#define g_ascii_isupper (
  c
)

Description

Determines whether a character is an ASCII upper case letter.

Unlike the standard C library isupper() function, this only recognizes standard ASCII letters and ignores the locale, returning FALSE for all non-ASCII characters. Also, unlike the standard library function, this takes 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.

This function is not directly available to language bindings.

Parameters

c

Type: -

Any character.
