NAME
rdma_create_id - Allocate a communication identifier.SYNOPSIS
#include <rdma/rdma_cma.h> int rdma_create_id (struct rdma_event_channel *channel, struct rdma_cm_id **id, void *context, enum rdma_port_space ps);ARGUMENTS
- channel
- The communication channel that events associated with the allocated rdma_cm_id will be reported on.
- id
- A reference where the allocated communication identifier will be returned.
- context
- User specified context associated with the rdma_cm_id.
- ps
- RDMA port space.
DESCRIPTION
Creates an identifier that is used to track communication information.NOTES
Rdma_cm_id's are conceptually equivalent to a socket for RDMA communication. The difference is that RDMA communication requires explicitly binding to a specified RDMA device before communication can occur, and most operations are asynchronous in nature. Communication events on an rdma_cm_id are reported through the associated event channel. Users must release the rdma_cm_id by calling rdma_destroy_id.PORT SPACE
Details of the services provided by the different port spaces are outlined below.- RDMA_PS_TCP
- Provides reliable, connection-oriented QP communication. Unlike TCP, the RDMA port space provides message, not stream, based communication.
- RDMA_PS_UDP
- Provides unreliable, connectionless QP communication. Supports both datagram and multicast communication.
