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

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).

RDMA_RESOLVE_ADDR(3)					   Librdmacm Programmer's Manual				      RDMA_RESOLVE_ADDR(3)

NAME

       rdma_resolve_addr - Resolve destination and optional source addresses.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       int rdma_resolve_addr (struct rdma_cm_id *id, struct sockaddr *src_addr, struct sockaddr *dst_addr, int timeout_ms);

ARGUMENTS

       id	   RDMA identifier.

       src_addr    Source address information.	This parameter may be NULL.

       dst_addr    Destination address information.

       timeout_ms  Time to wait for resolution to complete.

DESCRIPTION

       Resolve	destination  and  optional source addresses from IP addresses to an RDMA address.  If successful, the specified rdma_cm_id will be
       bound to a local 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

       This call is used to map a given destination IP address to a usable RDMA address.  The IP to RDMA address mapping is done using	the  local
       routing	tables,  or  via  ARP.	 If a source address is given, the rdma_cm_id is bound to that address, the same as if rdma_bind_addr were
       called.	If no source address is given, and the rdma_cm_id has not yet been bound to a device, then the	rdma_cm_id  will  be  bound  to  a
       source address based on the local routing tables.  After this call, the rdma_cm_id will be bound to an RDMA device.  This call is typically
       made from the active side of a connection before calling rdma_resolve_route and rdma_connect.

INFINIBAND SPECIFIC

       This call maps the destination and, if given, source IP addresses to GIDs.  In order to perform the mapping, IPoIB must be running on  both
       the local and remote nodes.
