rdma_bind_addr - Bind an RDMA identifier to a source address.

SYNOPSIS ARGUMENTS DESCRIPTION RETURN VALUE NOTES SEE ALSO

#include <rdma/rdma_cma.h>

int rdma_bind_addr (struct rdma_cm_id *id, struct sockaddr *addr);

id	RDMA identifier.
addr	Local address information. Wildcard values are permitted.

Associates a source address with an rdma_cm_id. The address may be wildcarded. If binding to a specific local address, the rdma_cm_id will also be bound to a local RDMA device.

Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason.

Typically, this routine is called before calling rdma_listen to bind to a specific port number, but it may also be called on the active side of a connection before calling rdma_resolve_addr to bind to a specific address.

If used to bind to port 0, the rdma_cm will select an available port, which can be retrieved with rdma_get_src_port(3).
