Deletes an EDMuser identified by its name from a remote EDMdatabase.
An EDMuser may not be deleted when it is connected to an EDMserver. Neither may it be deleted if it is the owner of data in the remote EDMdatabase.
Only the superuser may use this function.

Prototype:
EdmiError edmiRemoteDeleteUserBN(SdaiServerContext serverContextId,
SdaiString userName,
SdaiInvocationId *edmiInvocationId);
Arguments:
serverContextId |
Context identification, from edmiDefineServerContext |
userName |
The name of the EDMuser to be deleted. |
edmiInvocationId |

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an _EDMinterface_ error code. Use edmiGetErrorText to get the error text corresponding to the error code.

/* Delete User 'Lucy' and Give
all Lucys objects to Johnny. */
