This function is declared in the coresrv/ns/ns_api.h file.

Retcode NsEnumServices(NsHandle ns, const char *type, unsigned index,

char *server, rtl_size_t serverSize,

char *service, rtl_size_t serviceSize);

This function enumerates the endpoints with the defined interface that are published on the name server.

Input parameters:

ns is the handle of the connection with the name server that was previously received by using the NsCreate() call.
type is the name of the interface implemented by the endpoint (for example, kl.drivers.Block).
index is the index for enumerating endpoints.
serverSize is the maximum size of the buffer for the server output parameter in bytes.
serviceSize is the maximum size of the buffer for the service output parameter in bytes.

Output parameters:

server is the name of the server process that provides the endpoint (for example, kl.drivers.Ata).
service is the fully qualified name of the endpoint (for example, blkdev.ata).

For example, you can receive a full list of server processes that provide an endpoint with the kl.drivers.Block interface as follows.

rc = NsEnumServices(ns, "kl.drivers.Block", 0, outServerName, ServerNameSize, outServiceName, ServiceNameSize);

rc = NsEnumServices(ns, "kl.drivers.Block", 1, outServerName, ServerNameSize, outServiceName, ServiceNameSize);

...

rc = NsEnumServices(ns, "kl.drivers.Block", N, outServerName, ServerNameSize, outServiceName, ServiceNameSize);

Function calls with index incrementation continue until the function returns rcResourceNotFound.

If successful, the function returns rcOk, otherwise it returns an error code.
