RDMA_BIND_ADDR(3)     Librdmacm Programmer's ManualRDMA_BIND_ADDR(3)

NAME        top

       rdma_bind_addr - Bind an RDMA identifier to a source address.

SYNOPSIS        top

#include <rdma/rdma_cma.h>int rdma_bind_addr (struct rdma_cm_id *id, struct sockaddr *addr);

ARGUMENTS        top

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

DESCRIPTION        top

       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        top

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

NOTES        top

       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).
