NAME

       rdma_post_recv - post a work request to receive an incoming message.

SYNOPSIS

       #include <rdma/rdma_verbs.h>

       int  rdma_post_recv  (struct rdma_cm_id *id, void *context, void *addr,
       size_t length, struct ibv_mr *mr);

ARGUMENTS

       id          A reference to a communication identifier where the message
                   buffer will be posted.

       context     User-defined context associated with the request.

       addr        The address of the memory buffer to post.

       length      The length of the memory buffer.

       mr          A  registered  memory  region  associated  with  the posted
                   buffer.

DESCRIPTION

       Posts a work request to the receive queue of the queue pair  associated
       with  the  rdma_cm_id.   The posted buffer will be queued to receive an
       incoming message sent by the remote peer.

RETURN VALUE

       Returns 0 on success, or -1 on error.  If an error occurs,  errno  will
       be set to indicate the failure reason.

NOTES

       The  user  is  responsible for ensuring that a receive buffer is posted
       and large enough to contain all sent data before  the  peer  posts  the
       corresponding   send  message.   The  message  buffer  must  have  been
       registered before being posted, with the mr parameter  referencing  the
       registration.   The  buffer  must  remain  registered until the receive
       completes.

       Messages may be posted to an rdma_cm_id only after  a  queue  pair  has
       been  associated with it.  A queue pair is bound to an rdma_cm_id after
       calling  rdma_create_ep  or  rdma_create_qp,  if  the   rdma_cm_id   is
       allocated using rdma_create_id.

       The  user-defined  context  associated with the receive request will be
       returned to the user through the work completion  wr_id,  work  request
       identifier, field.
