READLINK(2)               OpenBSD Programmer's Manual              READLINK(2)

     readlink - read value of a symbolic link

     #include <unistd.h>

     readlink(const char *path, char *buf, size_t bufsiz);

     readlink() places the contents of the symbolic link path in the buffer
     buf, which has size bufsiz. readlink does not append a NUL character to

     The call returns the count of characters placed in the buffer if it suc-
     ceeds, or a -1 if an error occurs, placing the error code in the global
     variable errno.

     readlink() will fail if:

     [ENOTDIR]     A component of the path prefix is not a directory.

                   A component of a pathname exceeded {NAME_MAX} characters,
                   or an entire path name exceeded {PATH_MAX} characters.

     [ENOENT]      The named file does not exist.

     [EACCES]      Search permission is denied for a component of the path

     [ELOOP]       Too many symbolic links were encountered in translating the

     [EINVAL]      The named file is not a symbolic link.

     [EIO]         An I/O error occurred while reading from the file system.

     [EFAULT]      buf extends outside the process's allocated address space.

     lstat(2),  stat(2),  symlink(2),  symlink(7)

     The readlink() function call appeared in 4.2BSD.
