NAME¶
rdma_listen - Listen for incoming connection requests.
SYNOPSIS¶
#include <rdma/rdma_cma.h>
int rdma_listen (struct rdma_cm_id *id, int
backlog);
ARGUMENTS¶
- id
- RDMA identifier.
- backlog
- backlog of incoming connection requests.
DESCRIPTION¶
Initiates a listen for incoming connection requests or datagram service lookup.
The listen will be restricted to the locally bound source address.
RETURN VALUE¶
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to
indicate the failure reason.
NOTES¶
Users must have bound the rdma_cm_id to a local address by calling
rdma_bind_addr before calling this routine. If the rdma_cm_id is bound to a
specific IP address, the listen will be restricted to that address and the
associated RDMA device. If the rdma_cm_id is bound to an RDMA port number
only, the listen will occur across all RDMA devices.
