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