       SP_connect - Connect an application to a daemon


       #include <sp.h>
       int  SP_connect(  const  char  *spread_name,  const  char *private_name, int priority, int
       group_membership, mailbox *mbox, char *private_group);


       SP_connect is the initial call an application must make to establish a connection  with  a
       Spread  daemon.   All  other  spread  calls  must  refer  to a valid mbox returned by this

       The spread_name is the name of the Spread daemon to connect to.  It should be a string  in
       one of the following forms:

              4803   This  will connect to the Spread daemon on the local machine running on port
                     4803.  This form cannot be used to connect to a Windows95/NT machine.

                     This will also connect to the Spread daemon on the local machine running  on
                     port 4803.  This form can be used on Windows95/NT machines.

     or 4803@
                     This  will  connect  to  the  machine identified by either domain name or IP
                     address at the specified port.

       The private_name is the name this connection would like to be known as.  It must be unique
       on  the  machine  running  the spread daemon.  The name can be of at most MAX_PRIVATE_NAME
       characters, with the same character restrictions as a group name (mainly it cannot contain
       the  '#'  character). If the application does not care what name it uses, it can pass in a
       NULL pointer into this field and the daemon will assign the connection  a  unique,  random

       The  priority is a 0/1 flag for whether this connection will be a "Priority" connection or
       not. Currently this has no effect.

       The group_membership is a boolean integer.  If 1 then the application will  receive  group
       membership  messages  for  this connection, if 0 then the application will not receive any
       membership change messages.

       The mbox should be a pointer to a mailbox variable.  After  the  SP_connect  call  returns
       this variable will hold the mbox for the connection.

       The  private_group  should  be  a  pointer  to  a  string  big  enough  to  hold  at least
       MAX_GROUP_NAME characters.  After the Connect call returns it  will  contain  the  private
       group  name  of  this connection.  This group name can be used to send unicast messages to
       this connection and no one can join this special group.


       Returns ACCEPT_SESSION on success or one of the following errors ( < 0 ):

               The spread_name given to connect to was illegal for some reason.  Usually  because
               it  was a unix socket on Windows95/NT, an improper format for a host or an illegal
               port number

               Lower level socket calls failed to allow a  connection  to  the  specified  spread
               daemon right now.

               During  communication  to  establish  the  connection errors occured and the setup
               could not be completed.

               The daemon or library has a version mismatch.

               This is a protocol error which should not occur if the connection request is  sent
               correctly  to  the  daemon. It means that the length of the user name was not sent
               (if no user name is provided a length of 0 must be sent).

               Name provided violated some requirement (length or used an illegal character)

               Name provided is not unique on this daemon. Recommended response is to  try  again
               with a different name.
