The POXIX prototype for readlink(2) is:
ssize_t readlink(const char *restrict path, char *restrict buf, size_t 
bufsize);

See:
http://www.opengroup.org/onlinepubs/000095399/functions/readlink.html

NetBSD already did it:
http://netbsd.gw.com/cgi-bin/man-cgi?readlink+2+

It'd be good have it corrected in 7.0.

Salutes,
Igh.
