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.
