IBND_DISCOVER_FABRIC(3) 	    OpenIB Programmer's Manual		  IBND_DISCOVER_FABRIC(3)

NAME
       ibnd_discover_fabric,  ibnd_destroy_fabric,  ibnd_debug	ibnd_show_progress  -  initialize
       ibnetdiscover library.

SYNOPSIS
       #include <infiniband/ibnetdisc.h>

       void ibnd_destroy_fabric(ibnd_fabric_t *fabric)
       void ibnd_debug(int i)
       void ibnd_show_progress(int i)
       int ibnd_set_max_smps_on_wire(int i)

DESCRIPTION
       ibnd_discover_fabric() Discover the fabric connected to the port specified by  ibmad_port,
       using a timeout specified.  The "from" and "hops" parameters are optional and allow one to
       scan part of a fabric by specifying a node "from" and a number of hops away from that node
       to  scan,  "hops".   This  gives the user a "sub-fabric" which is "centered" anywhere they
       chose.

       ibmad_port must be opened with at least IB_SMI_CLASS and IB_SMI_DIRECT_CLASS  classes  for
       ibnd_discover_fabric to work.

       ibnd_destroy_fabric() free all memory and resources associated with the fabric.

       ibnd_debug() Set the debug level to be printed as library operations take place.

       ibnd_show_progress()  Indicate that the library should print debug output which shows it's
       progress through the fabric.

       ibnd_set_max_smps_on_wire() Set the number of SMP's which  will	be  issued  on	the  wire
       simultaneously.

RETURN VALUE
       ibnd_discover_fabric() return NULL on failure, otherwise a valid ibnd_fabric_t object.

       ibnd_destory_fabric(), ibnd_debug() NONE

       ibnd_set_max_smps_on_wire() The previous value is returned

EXAMPLES
       Discover the entire fabric connected to device mthca0 , port 1.

	    int  mgmt_classes[2]  =  {IB_SMI_CLASS,  IB_SMI_DIRECT_CLASS};	struct ibmad_port
       *ibmad_port = mad_rpc_open_port(ca, ca_port, mgmt_classes, 2);	   ibnd_fabric_t  *fabric
       =  ibnd_discover_fabric(ibmad_port, 100, NULL, 0);      ...	 ibnd_destroy_fabric(fab-
       ric);	  mad_rpc_close_port(ibmad_port);

       Discover only a single node and those nodes connected to it.

	    ...        str2drpath(&(port_id.drpath),  from,  0,  0);	    ... 	ibnd_dis-
       cover_fabric(ibmad_port, 100, &port_id, 1);	...
