+"Passing a Factor string to a C function expecting a C string allocates a " { $link byte-array } " in the Factor heap; the string is then converted to the requested format and a raw pointer is passed to the function."
+$nl
+"If the conversion fails, for example if the string contains null bytes or characters with values higher than 255, a " { $link c-string-error. } " is thrown."
+$nl
+"Care must be taken if the C function expects a " { $link char* } " with a length in bytes, rather than a null-terminated " { $link char* } "; passing the result of calling " { $link length } " on the string object will not suffice. This is because a Factor string of " { $emphasis "n" } " characters will not necessarily encode to " { $emphasis "n" } " bytes. The correct idiom for C functions which take a string with a length is to first encode the string using " { $link encode } ", and then pass the resulting byte array together with the length of this byte array."
+$nl
+"Sometimes a C function has a parameter type of " { $link void* } ", and various data types, among them strings, can be passed in. In this case, strings are not automatically converted to aliens, and instead you must call one of these words:"
+{ $subsection string>alien }
+{ $subsection malloc-string }
+"The first allocates " { $link byte-array } "s, and the latter allocates manually-managed memory which is not moved by the garbage collector and has to be explicitly freed by calling " { $link free } ". See " { $link "byte-arrays-gc" } " for a discussion of the two approaches."
+$nl
+"A word to read strings from arbitrary addresses:"
+{ $subsection alien>string }
+"For example, if a C function returns a " { $link char* } " but stipulates that the caller must deallocate the memory afterward, you must define the function as returning " { $link void* } ", and call one of the above words before passing the pointer to " { $link free } "." ;

+"The " { $vocab-link "furnace.recaptcha" } " vocabulary implements support for the Recaptcha. Recaptcha is a web service that provides the user with a captcha, a test that is easy to solve by visual inspection, but hard to solve by writing a computer program. Use a captcha to protect forms from abusive users." $nl
+
+"The recaptcha responder is a " { $link filter-responder } " that wraps another responder. Set the " { $slot "domain" } ", " { $slot "public-key" } ", and " { $slot "private-key" } " slots of this responder to your Recaptcha account information." $nl

+! DESCRIPTION
+! -----------
+
+! Consider the fraction, n/d, where n and d are positive integers.
+! If n<d and HCF(n,d)=1, it is called a reduced proper fraction.
+
+! If we list the set of reduced proper fractions for d ≤ 8 in ascending order
+! of size, we get:
+
+! 1/8, 1/7, 1/6, 1/5, 1/4, 2/7, 1/3, 3/8, 2/5, 3/7, 1/2, 4/7, 3/5, 5/8, 2/3,
+! 5/7, 3/4, 4/5, 5/6, 6/7, 7/8
+
+! It can be seen that there are 21 elements in this set.
+
+! How many elements would be contained in the set of reduced proper fractions
+! for d ≤ 1,000,000?
+
+
+! SOLUTION
+! --------
+
+! The answer can be found by adding totient(n) for 2 ≤ n ≤ 1e6

+
+! DESCRIPTION
+! -----------
+
+! The number 145 is well known for the property that the sum of the factorial
+! of its digits is equal to 145:
+
+! 1! + 4! + 5! = 1 + 24 + 120 = 145
+
+! Perhaps less well known is 169, in that it produces the longest chain of
+! numbers that link back to 169; it turns out that there are only three such
+! loops that exist:
+
+! 169 → 363601 → 1454 → 169
+! 871 → 45361 → 871
+! 872 → 45362 → 872
+
+! It is not difficult to prove that EVERY starting number will eventually get
+! stuck in a loop. For example,
+
+! 69 → 363600 → 1454 → 169 → 363601 (→ 1454)
+! 78 → 45360 → 871 → 45361 (→ 871)
+! 540 → 145 (→ 145)
+
+! Starting with 69 produces a chain of five non-repeating terms, but the
+! longest non-repeating chain with a starting number below one million is sixty
+! terms.
+
+! How many chains, with a starting number below one million, contain exactly
+! sixty non-repeating terms?

+! -----------
+
+! The radical of n, rad(n), is the product of distinct prime factors of n.
+! For example, 504 = 2^3 × 3^2 × 7, so rad(504) = 2 × 3 × 7 = 42.
+
+! If we calculate rad(n) for 1 ≤ n ≤ 10, then sort them on rad(n),
+! and sorting on n if the radical values are equal, we get:
