NAME

     fhreadlink — read value of a symbolic link

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/param.h>
     #include <sys/mount.h>

     int
     fhreadlink(fhandle_t *fhp, char *buf, size_t bufsize);

DESCRIPTION

     The fhreadlink() system call places the contents of the symbolic link fhp in the buffer buf,
     which has size bufsiz.  The fhreadlink() system call does not append a NUL character to buf.

RETURN VALUES

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

ERRORS

     The readlink() system call will fail if:

     [ENOENT]           The named file does not exist.

     [ELOOP]            Too many symbolic links were encountered in translating the file handle
                        fhp.

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

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

     [EINTEGRITY]       Corrupted data was detected while reading from the file system.

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

     [ESTALE]           The file handle fhp is no longer valid
