    Command:

    ipq_set_mode

    
    
    

    SYNOPSIS

           #include <linux/netfilter.h>
           #include <libipq.h>
    
           int  ipq_set_mode(const  struct  ipq_handle  *h,  u_int8_t mode, size_t
           range);
    
    
    

    DESCRIPTION

           The ipq_set_mode function sends a message to the kernel  ip_queue  mod-
           ule,  specifying  whether  packet  metadata only, or packet payloads as
           well as metadata should be copied to userspace.
    
           The h parameter is a context handle which  must  previously  have  been
           returned successfully from a call to ipq_create_handle.
    
           The mode parameter must be one of:
    
           IPQ_COPY_META
                  Copy only packet metadata to userspace.
    
           IPQ_COPY_PACKET
                  Copy packet metadata and packet payloads to userspace.
    
           The range parameter is used to specify how many bytes of the payload to
           copy to userspace.  It is only valid for IPQ_COPY_PACKET  mode  and  is
           otherwise  ignored.   The  maximum  useful  value  for  range  is 65535
           (greater values will be clamped to this by ip_queue).
    
           ipq_set_mode is usually used immediately following ipq_create_handle to
           enable the flow of packets to userspace.
    
           Note  that as the underlying Netlink messaging transport is connection-
           less, the ip_queue module does not know that a userspace application is
           ready to communicate until it receives a message such as this.
    
    
    

    RETURN VALUE

           On failure, -1 is returned.
           On success, a non-zero positive value is returned.
    
    
    

    ERRORS

           On  failure,  a  descriptive  error  message  will be available via the
           ipq_errstr function.
    
    
    

    DIAGNOSTICS

           A relatively common failure may occur if the  ip_queue  module  is  not
           loaded.  In this case, the following code excerpt:
    
                  status = ipq_set_mode(h, IPQ_COPY_META, 0);
                  if (status < 0) {
                       ipq_perror("myapp");
                       ipq_destroy_handle(h);
                       exit(1);
