NAME

       rpma_conn_req_recv - initiate the receive operation

SYNOPSIS

             #include <librpma.h>

             struct rpma_conn_req;
             struct rpma_mr_local;
             int rpma_conn_req_recv(struct rpma_conn_req *req, struct rpma_mr_local *dst, size_t offset,
                             size_t len, const void *op_context);

DESCRIPTION

       rpma_conn_req_recv()  initiates  the receive operation. It prepares a buffer for a message
       sent from other side of the connection. Please see rpma_send(3).  This  is  a  variant  of
       rpma_recv(3)  which  may  be  used  before  the  connection  is established. op_context is
       returned in the wr_id field of the completion (struct ibv_wc).

RETURN VALUE

       The rpma_conn_req_recv() function returns 0  on  success  or  a  negative  error  code  on
       failure.

ERRORS

       rpma_conn_req_recv() can fail with the following errors:

       •  RPMA_E_INVAL - req or src or op_context is NULL

       •  RPMA_E_PROVIDER - ibv_post_recv(3) failed
