|
|
.SH SYNOPSIS
|
|
.B "#include <rdma/rdma_verbs.h>"
|
|
.P
|
|
.B "int" rdma_get_send_comp
|
|
.BI "(struct rdma_cm_id *" id ","
|
|
.BI "struct ibv_wc *" wc ");"
|
|
.SH ARGUMENTS
|
|
.IP "id" 12
|
|
A reference to a communication identifier to check for completions.
|
|
.IP "wc" 12
|
|
A reference to a work completion structure to fill in.
|
|
.SH "DESCRIPTION"
|
|
Retrieves a completed work request for a send, RDMA read, or RDMA write
|
|
operation. Information about the completed request is returned through
|
|
the wc parameter, with the wr_id set to the context of the request. For
|
|
details on the work completion structure, see ibv_poll_cq.
|
|
.SH "RETURN VALUE"
|
|
Returns the number of returned completions (0 or 1) on success, or -1 on error.
|
|
If an error occurs, errno will be set to indicate the failure reason.
|
|
.SH "NOTES"
|
|
This calls polls the send completion queue associated with an rdma_cm_id.
|
|
If a completion is not found, the call blocks until a request completes.
|
|
This call should only be used on rdma_cm_id's that do not share CQs
|
|
with other rdma_cm_id's, and maintain separate CQs for sends and receive
|
|
completions.
