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

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). SEE ALSO

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

rdma_join_multicast - Joins a multicast group. SYNOPSIS
#include <rdma/rdma_cma.h> int rdma_join_multicast (struct rdma_cm_id *id, struct sockaddr *addr, void *context); ARGUMENTS
id Communication identifier associated with the request. addr Multicast address identifying the group to join. context User-defined context associated with the join request. DESCRIPTION
Joins a multicast group and attaches an associated QP to the group. RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason. NOTES
Before joining a multicast group, the rdma_cm_id must be bound to an RDMA device by calling rdma_bind_addr or rdma_resolve_addr. Use of rdma_resolve_addr requires the local routing tables to resolve the multicast address to an RDMA device, unless a specific source address is provided. The user must call rdma_leave_multicast to leave the multicast group and release any multicast resources. After the join opera- tion completes, if a QP is associated with the rdma_cm_id, it is automatically attached to the multicast group when the multicast event is retrieved by the user. Otherwise, the user is responsible for calling ibv_attach_mcast to bind the QP to the multicast group. The join context is returned to the user through the private_data field in the rdma_cm_event.

Bind system call

We are calling the bind system call as below bind(sfd, (struct sockaddr *) &addr, sizeof(struct sockaddr_un));Why there is difference in third parameter getting the sizeof as "struct sockaddr_un", wherein the 2nd parametere we are passing it as "(struct sockaddr *)"? Regards, Sajjan (2 Replies)
