Subject: [Caml-list] Quick question - accessing variant value from C
Date: 28 Mar 2001 21:48:41 -0800 [thread overview]
Message-ID: <luelvh6s7a.fsf@hci.ucsd.edu> (raw)
In-Reply-To: Alex Baretta's message of "Sat, 17 Mar 2001 02:35:47 +0100"
I have a value of the following type being passed to an external:
type pointer = Null | Address of string
and I'd like to determine (in the C code) which variant the value is
and get the pointer to the string. I've stared at mlvalues.h for a
while, but I can't really figure it out. Can anyone help? You won't
regret it...
