IDebugPendingBreakpoint2::Enable

切换挂起断点的启用状态。

语法

int Enable(
    int fEnable
);

HRESULT Enable(
    BOOL fEnable
);

参数

fEnable
[in]设置为非零（TRUE）以启用挂起的断点，或设置为零（FALSE）以禁用。

返回值

如果成功，则返回 S_OK；否则，返回错误代码。 返回 E_BP_DELETED 是否已删除断点。

备注

启用或禁用挂起断点时，从该断点绑定的所有断点都设置为相同的状态。

即使断点已启用或禁用，也可以根据需要多次调用此方法。

示例

以下示例演示如何为公开 IDebugPendingBreakpoint2 接口的简单CPendingBreakpoint对象实现此方法。

HRESULT CPendingBreakpoint::Enable(BOOL fEnable)
{
    HRESULT hr;

    // Verify that the pending breakpoint has not been deleted. If deleted,
    // then return hr = E_BP_DELETED.
    if (m_state.state != PBPS_DELETED)
    {
        // If the bound breakpoint member variable is valid, then enable or
        // disable the bound breakpoint.
        if (m_pBoundBP)
        {
            m_pBoundBP->Enable(fEnable);
        }
        // Set the PENDING_BP_STATE in the PENDING_BP_STATE_INFO structure
        // to enabled or disabled depending on the passed BOOL condition.
        m_state.state = fEnable ? PBPS_ENABLED : PBPS_DISABLED;
        hr = S_OK;

    }
    else
    {
        hr = E_BP_DELETED;
    }

    return hr;
}
