DAT_REGISTRY_ADD_PROVIDER(3DAT) Direct Access Transport Library Functions

NAME

dat_registry_add_provider - declare the Provider with the Dynamic
Registry

SYNOPSIS

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
)

PARAMETERS

provider
Self-description of a Provider.


provider_info
Attributes of the Provider.

DESCRIPTION

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.

RETURN VALUES

DAT_SUCCESS

The operation was successful.


DAT_INSUFFICIENT_RESOURCES

The maximum number of Providers was already registered.


DAT_INVALID_PARAMETER

Invalid parameter.


DAT_PROVIDER_ALREADY_REGISTERED

Invalid or nonunique name.
