NAME

       rdma_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).
