       int dpns_readlink (const char *path, char *buf, size_t bufsiz)

DESCRIPTION
       dpns_readlink reads the value of a symbolic link in the DPNS Name Server.

       path   specifies the link name relative to the current DPNS directory or the full DPNS pathname.

       buf    points at a buffer to receive the value.

       bufsiz gives the buffer size.
