Ctype - Perl extension for character class testing

  use Ctype qw(toupper);
  # plain style
  $uppercased = toupper("a");
  # OO style
  $obj = Ctype->new("a");
  $uppercased = $obj->uppercased;

Ctype provides character class testing to Perl programs. The ctype.h functions are part of the C library (in your system!). Ctype also supports the Perl library ctype functions. To use the Perl library ctype functions, set the variable $Ctype::useperlfns to a non-false value. For the OO interface, call the method $obj->useperlfns to toggle it.

The OO interface constructor is called (by convention) new. new is called with a character as an argument. It creates a Ctype object that will perform tests on the character when called as an object method. These are the relations to the regular C functions:

	isalphanumeric		isalnum
	isalphabetic		isalpha
	isnumerical		isdigit
	islowercase		islower
	iswhitespace		isspace
	isuppercase		isupper
	ishexdigit		isxdigit

	tolowercase		tolower
	touppercase		toupper

The setchar method sets the character stored in the object.
