READLINK(2)                          SysV                          READLINK(2)



NAME
     readlink - read value of a symbolic link

SYNOPSIS
     cc = readlink(path, buf, bufsiz)
     int cc;
     char *path, *buf;
     int bufsiz;

DESCRIPTION
     readlink places the contents of the symbolic link named by path into the
     buffer buf, which has size bufsiz.  The contents of the link are not null
     terminated when returned.

ERRORS
     readlink will fail and the mode of the file named by path will be
     unchanged if:

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

     [EINVAL]         The pathname contains a character with the high-order
                      bit set.

     [ENAMETOOLONG]   A component of a pathname exceeded 255 characters, or an
                      entire path name exceeded 1023 characters.

     [ENOENT]         The named file does not exist.

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

     [ELOOP]          The call encountered too many symbolic links in
                      translating the pathname.

     [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' allocated address
                      space.

SEE ALSO
     stat(2).

DIAGNOSTICS
     A successful call returns the number of characters in buf.  A failed call
     returns -1 and sets errno as indicated under "Errors."
