Function Macro

GLibascii_isupper

Declaration [src]

#define g_ascii_isupper (
  c
)

Description [src]

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.

Parameters

c -
 

Any character.
