int KmlIssCgCleanDI(KmlSolverTask **handle);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| handle | KmlSolverTask \*\* | 求解器句柄，传入之前步骤的变量。 | 输入/输出 |


#### 返回值

| 返回值 | 类型 | 描述 |
| --- | --- | --- |
| KMLSS\_NO\_ERROR | int | 正常执行。 |
| KMLSS\_NULL\_ARGUMENT | int | handle为空参数。 |


#### 依赖

#include "kml_iss.h"
