const void
*op_context);
Overview
rpma_send_with_imm() initiates the send operation with immediate data which transfers a message from the local memory to other side of the connection. To send a 0 byte message, set src to NULL and both offset and len to 0.
The attribute flags set the completion notification indicator:
- •
-
RPMA_F_COMPLETION_ON_ERROR - generate the completion on error
- •
-
RPMA_F_COMPLETION_ALWAYS - generate the completion regardless of result of the operation.
op_context is returned in the wr_id field of the completion (struct ibv_wc).
Return value
The rpma_send_with_imm() function returns 0 on success or a negative error code on failure.
Errors
rpma_send_with_imm() can fail with the following errors:
- •
-
RPMA_E_INVAL - conn == NULL || flags == 0
- •
-
RPMA_E_INVAL - src == NULL && (offset != 0 || len != 0)
- •
-
RPMA_E_PROVIDER - ibv_post_send(3) failed
