RDMA_BIND_ADDR(3) Librdmacm Programmer's Manual RDMA_BIND_ADDR(3)NAMErdma_bind_addr - Bind an RDMA identifier to a source address.
SYNOPSIS
#include <rdma/rdma_cma.h>
int rdma_bind_addr (struct rdma_cm_id *id, struct sockaddr *addr);
ARGUMENTS
id RDMA identifier.
addr Local address information. Wildcard values are permitted.
DESCRIPTION
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.
RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will
be set to indicate the failure reason.
NOTES
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).
