RDMA_REJECT(3)        Librdmacm Programmer's Manual        RDMA_REJECT(3)

NAME         top

       rdma_reject - Called to reject a connection request.

SYNOPSIS         top

       #include <rdma/rdma_cma.h>

       int rdma_reject (struct rdma_cm_id *id, const void *private_data,
       uint8_t private_data_len);

ARGUMENTS         top

       id          Connection identifier associated with the request.

       private_data
                   Optional private data to send with the reject message.

       private_data_len
                   Specifies the size of the user-controlled data buffer.
                   Note that the actual amount of data transferred to the
                   remote side is transport dependent and may be larger
                   than that requested.

DESCRIPTION         top

       Called from the listening side to reject a connection or datagram
       service lookup request.

RETURN VALUE         top

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

NOTES         top

       After receiving a connection request event, a user may call
       rdma_reject to reject the request.  If the underlying RDMA
       transport supports private data in the reject message, the
       specified data will be passed to the remote side.
