NAME
     libdat - direct access transport library

SYNOPSIS
     cc [ flag... ] file... -ldat [ library... ]
     #include 


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 shared object interfaces.

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 configuration  program  should  be
     used  to  add  and  remove service provider's entries in the
     system-wide dat.conf(4).
