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

110 The libdat library supports service providers written according to the
111 uDAPL 1.2 specification. A service provider library has to be a dynamic
112 loadable shared object with two public entry points exported:
113 dat_provider_init dat_provider_fini
118 In terms of installation, the service provider package should include a
122 service_provider.conf(4) file. The datadm(1M) administrative configura‐
123 tion program should be used to add and remove service provider's
124 entries in the system-wide dat.conf(4).
