NAME

       libdat - direct access transport library

SYNOPSIS

       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

DESCRIPTION

       The  libdat  library provides an application with the User Direct Access Programming Library (uDAPL) 1.2 functions to access the underlying
       RDMA-able interconnects. Different uDAPL service providers listed in the DAT static registry dat.conf(4) can be registered  during  runtime
       with  the  DAT library. After an application opens an interface adapter belonging to a particular service provider, all function calls will
       be redirected to that service provider's library.

INTERFACES

       The shared object libdat.so.1 provides the public interfaces defined below for applications. See intro(3)  for  additional  information  on

NOTES

       The  libdat  library  supports  service  providers written according to the uDAPL 1.2 specification. A service provider library has to be a
       dynamic loadable shared object with two public entry points exported:

       dat_provider_init             dat_provider_fini

       In terms of installation, the service provider package should include a service_provider.conf(4) file. The datadm(1M)  administrative  con-
       figuration program should be used to add and remove service provider's entries in the system-wide dat.conf(4).
