I've committed a corresponding change to the fopencookie(3) man page.

@@ -158,7 +158,8 @@ As its function result, the
 .I write
 function should return the number of bytes copied from
 .IR buf ,
-or \-1 on error.
+or 0 on error.
+(The function must not return a negative value.)
 The
 .I write
 function should update the stream offset appropriately.

Then this is a documentation bug - 12.21.3.2 Custom Stream Hook Functions says:

   You should define the function to write data to the cookie as:

     ssize_t WRITER (void *COOKIE, const char *BUFFER, size_t SIZE)

   This is very similar to the `write' function; see *note I/O
Primitives::.  Your function should transfer up to SIZE bytes from the
buffer, and return the number of bytes written.  You can return a value
of `-1' to indicate an error.
