The `sx` egg does something similar -- transforming a list of strings into a null-terminated array of C strings. I derived a quick example from it and attached the code. $ csc -X easyffi -s stringlist.scm $ csi -q -R stringlist #;1> (my-foo (list "bar" "baz" "quux")) string 0: bar string 1: baz string 2: quux An example of the opposite transformation (null-terminated C string array to a vector of Scheme strings) can be found in the `hostinfo` egg under array0->string-vector.
