ICLRDebugManager::BeginConnection Method

  • Article

Establishes a new connection between the host and the debugger to associate a list of tasks with an identifier and a friendly name.

Syntax

HRESULT BeginConnection (  
    [in] CONNID dwConnectionId,  
    [in, string] wchar_t* szConnectionName  
);

Parameters

dwConnectionId
[in] An identifier to associate with the list of common language runtime (CLR) tasks.

szConnectionName
[in] A friendly name to associate with the list of CLR tasks.

Return Value

HRESULT Description
S_OK BeginConnection returned successfully.
HOST_E_CLRNOTAVAILABLE The CLR has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
E_INVALIDARG dwConnectionId was zero, or BeginConnection was already called using this dwConnectionId value, or szConnectionName was null.
E_OUTOFMEMORY Not enough memory could be allocated to hold the list of tasks associated with this connection.

Remarks

ICLRDebugManager provides three methods, BeginConnection, SetConnectionTasks, and EndConnection, for associating task lists with identifiers and friendly names.

Important

These three methods must be called in a specific order for each set of tasks. BeginConnection is called first to establish a new connection. SetConnectionTasks is called next to provide the set of tasks to be associated with that connection. EndConnection is called last to remove the association between the task list and the identifier and friendly name.However, calls for different connections can be nested.
