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.
