169  * These extended I/O function callbacks echo the BSD socket API but accept
170  * an extra pointer parameter at the end of their argument list that can
171  * be used by client applications for their own needs.  For some of the calls,
172  * the pointer is a session argument of type struct lextiof_session_private *
173  * that is associated with the LDAP session handle (LDAP *).  For others, the
174  * pointer is a socket specific struct lextiof_socket_private * argument that
175  * is associated with a particular socket (a TCP connection).
176  *
177  * The lextiof_session_private and lextiof_socket_private structures are not
178  * defined by the LDAP C API; users of this extended I/O interface should
179  * define these themselves.
180  *
181  * The combination of the integer socket number (i.e., lpoll_fd, which is
182  * the value returned by the CONNECT callback) and the application specific
183  * socket argument (i.e., lpoll_socketarg, which is the value set in *sockargpp
184  * by the CONNECT callback) must be unique.
185  *
186  * The types for the extended READ and WRITE callbacks are actually in lber.h.
187  *
188  * The CONNECT callback gets passed both the session argument (sessionarg)
189  * and a pointer to a socket argument (socketargp) so it has the
190  * opportunity to set the socket-specific argument.  The CONNECT callback
191  * also takes a timeout parameter whose value can be set by calling
192  * ldap_set_option( ld, LDAP_X_OPT_..., &val ).  The units used for the
193  * timeout parameter are milliseconds.
194  *
195  * A POLL interface is provided instead of a select() one.  The timeout is
196  * in milliseconds.
197 
198  * A NEWHANDLE callback function is also provided.  It is called right
199  * after the LDAP session handle is created, e.g., during ldap_init().
200  * If the NEWHANDLE callback returns anything other than LDAP_SUCCESS,
201  * the session handle allocation fails.
202  *
203  * A DISPOSEHANDLE callback function is also provided.  It is called right
204  * before the LDAP session handle and its contents are destroyed, e.g.,
205  * during ldap_unbind().
