>Description:
Both man page and /usr/include/unistd.h show that the system call readlink does not confirm to IEEE Std 1003.1, 2004 Edition, which requres the following declaration:
--------
#include <unistd.h>
ssize_t readlink(const char *restrict path, char *restrict buf,
size_t bufsize);
--------
On FreeBSD the declearation is:
--------
/* 1003.1-2001 */
#if __POSIX_VISIBLE >= 200112 || __XSI_VISIBLE
int fchown(int, uid_t, gid_t);
int readlink(const char *, char *, int);
#endif
--------
>How-To-Repeat:
man readlink or view the file /usr/include/unistd.h
