SYNOPSIS

      #include <librpma.h>

      struct ibv_context;
      struct rpma_peer;
      int rpma_peer_new(struct ibv_context *ibv_ctx,
                      struct rpma_peer **peer_ptr);

• RPMA_E_INVAL - ibv_ctx or peer_ptr is NULL

• RPMA_E_NOMEM - creating a verbs protection domain failed with ENOMEM.

• RPMA_E_PROVIDER - creating a verbs protection domain failed with error other than ENOMEM.

• RPMA_E_UNKNOWN - creating a verbs protection domain failed without error value.

• RPMA_E_NOMEM - out of memory
