SCGetUserInfo(3)		 Impressario		      SCGetUserInfo(3)

NAME
     SCGetUserInfo - Get information about who is using a scanner

SYNOPSIS
     #include <stdio.h>
     #include <scanner.h>

     int SCGetUserInfo(char *scanner, char **login, char **name,
		       char **hostName);

DESCRIPTION
     SCGetUserInfo can be used after a call to SCOpen(3) has failed with
     SCerrno set to EBUSY.  SCGetUserInfo returns the login name and the real
     name of the user who has the scanner open, and the host name of machine
     on which the scanner is open.

     if SCGetUserInfo is called at any time other than right after SCOpen has
     failed with SCerrno set to EBUSY, information about the last person to
     have used the scanner is returned.

RETURN VALUE
     SCGetUserInfo returns 0 if it is successful, or -1 if there is an error.

     In the event of an error, SCGetUserInfo sets SCerrno to indicate the
     reason.

EXECUTION ERROR CODES
     SCGetUserInfo will fail under the following circumstances.

     SCENOSCANNER	      No such scanner

     SCENOSCANNERS	      No scanners are installed

     SCENOMEM		      Out of memory

     SCEDRVMSG		      Driver specific error.  SCErrorString(3) will
			      return a custom message supplied by the scanner
			      driver

     In addition, SCGetUserInfo may fail as the result of a failed system
     call, in which case SCerrno will be set to a value from <sys/errno.h>.
