- declare the Provider with the Dynamic Registry
cc [ flag… ] file… -ldat [ library… ] #include <dat/udat.h> DAT_RETURN dat_registry_add_provider ( IN const DAT_PROVIDER *provider, IN const DAT_PROVIDER_INFO *provider_info )
Self-description of a Provider.
Attributes of the Provider.
The Provider declares itself with the Dynamic Registry. Note that the caller can choose to register itself multiple times, for example once for each port. The choice of what to virtualize is up to the Provider. Each registration provides an Interface Adapter to DAT. Each Provider must have a unique name.
The same IA Name cannot be added multiple times. An attempt to register the same IA Name again results in an error with the return value DAT_PROVIDER_ALREADY_REGISTERED.
The contents of provider_info must be the same as those the Consumer uses in the call to dat_ia_open(3DAT) directly, or the ones provided indirectly defined by the header files with which the Consumer compiled.
The operation was successful.
The maximum number of Providers was already registered.
Invalid or nonunique name.
