       rdma_post_write - post an RDMA write work request.


       #include <rdma/rdma_verbs.h>

       int  rdma_post_write (struct rdma_cm_id *id, void *context, void *addr,
       size_t length, struct ibv_mr  *mr,  int  flags,  uint64_t  remote_addr,
       uint32_t rkey);


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

       context     User-defined context associated with the request.

       addr        The local address of the source of the write request.

       length      The length of the write operation.

       mr          Optional memory region associated with the local buffer.

       flags       Optional flags used to control the write operation.

       remote_addr The address of the remote registered memory to write into.

       rkey        The  registered  memory  key  associated  with  the  remote


       Posts  a  work  request  to the send queue of the queue pair associated
       with the rdma_cm_id.  The contents of the local  data  buffer  will  be
       writen into the remote memory region.


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


       For a list of supported flags, see ibv_post_send.  Unless  inline  data
       is  specified,  the  local data buffer must have been registered before
       the write is issued, and the buffer must remain  registered  until  the
       write completes.  The remote buffer must always be registered.

       Write   operations   may   not  be  posted  to  an  rdma_cm_id  or  the
       corresponding queue pair until it has been connected.

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