NAME

       rdma_create_id - Allocate a communication identifier.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       int   rdma_create_id   (struct   rdma_event_channel   *channel,  struct
       rdma_cm_id **id, void *context, enum rdma_port_space ps);

ARGUMENTS

       channel     The communication channel that events associated  with  the
                   allocated rdma_cm_id will be reported on.

       id          A  reference  where  the allocated communication identifier
                   will be returned.

       context     User specified context associated with the rdma_cm_id.

       ps          RDMA port space.

DESCRIPTION

       Creates an identifier that is used to track communication  information.

NOTES

       Rdma_cm_id’s   are   conceptually  equivalent  to  a  socket  for  RDMA
       communication.  The difference  is  that  RDMA  communication  requires
       explicitly  binding to a specified RDMA device before communication can
       occur, and most operations are asynchronous in  nature.   Communication
       events  on  an  rdma_cm_id  are  reported  through the associated event
       channel.  Users must release the rdma_cm_id by calling rdma_destroy_id.

PORT SPACE

       Details  of  the  services  provided  by  the different port spaces are
       outlined below.

       RDMA_PS_TCP
              Provides reliable, connection-oriented QP communication.  Unlike
              TCP,  the  RDMA  port  space provides message, not stream, based
              communication.

       RDMA_PS_UDP
              Provides unreliable, connectionless QP communication.   Supports
              both datagram and multicast communication.
