C creates a C, which is a reference to a newly created symbol (see the C package). If it receives any parameters, they are passed to C; if the open fails, the C object is destroyed. Otherwise, it is returned to the caller. C creates a C like C does. It requires two parameters, which are passed to C; if the fdopen fails, the C object is destroyed. Otherwise, it is returned to the caller. C accepts one parameter or two. With one parameter, it is just a front end for the built-in C function. With two parameters, the first parameter is a filename that may include whitespace or other special characters, and the second parameter is the open mode, optionally followed by a file permission value. If C receives a Perl mode string (">", "+<", etc.) or a POSIX fopen() mode string ("w
