19 The libdat library provides an application with the User Direct Access
20 Programming Library (uDAPL) 1.2 functions to access the underlying RDMA-able
21 interconnects. Different uDAPL service providers listed in the DAT static
22 registry \fBdat.conf\fR(4) can be registered during runtime with the DAT
23 library. After an application opens an interface adapter belonging to a
24 particular service provider, all function calls will be redirected to that
25 service provider's library.
29 The shared object \fBlibdat.so.1\fR provides the public interfaces defined
30 below for applications. See \fBIntro\fR(3) for additional information on shared

143 The \fBlibdat\fR library supports service providers written according to the
144 uDAPL 1.2 specification. A service provider library has to be a dynamic
145 loadable shared object with two public entry points exported:
151 \fBdat_provider_init\fR \fBdat_provider_fini\fR
156 In terms of installation, the service provider package should include a
157 \fBservice_provider.conf\fR(4) file. The \fBdatadm\fR(8) administrative
158 configuration program should be used to add and remove service provider's
159 entries in the system-wide \fBdat.conf\fR(4).
