Description: Reference for GLib.ascii_islower

### Function Macro

# GLibascii_islower

#### Declaration [src]

    #define g_ascii_islower (
      c
    )

#### Description [src]

Determines whether a character is an ASCII lower case letter.

Unlike the standard C library `islower()` 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.
