ifignore(SLIB)                 6 January 1993                 ifignore(SLIB)


 Name

    ifignore - check for ignored network interface

 Syntax


    int ifignore( if_name, serv_name )
    char *if_name, *serv_name;


 Description

    ifignore provides a filtering mechanism for network applications which
    would otherwise indiscriminately send packets over all network interfaces
    attached to the machine.  The function consults the file /etc/if.ignore
    and returns a value to indicate whether or not a particular network
    interface should be ``ignored'' by the invoking server.  This indication
    should then be used by the server itself in determining how to deal with
    the interface in question.  ifignore returns a non-zero value if ifname
    should be ignored by servname; otherwise, zero is returned.
