# KmlDssSymClean?I

#### 接口定义

C Interface：

int KmlDssSymCleanSI(KmlSolverTask **pHandle);

int KmlDssSymCleanDI(KmlSolverTask **pHandle);

int KmlDssSymCleanCI(KmlSolverTask **pHandle);

int KmlDssSymCleanZI(KmlSolverTask **pHandle);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| pHandle | 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 | 无效的参数。 |
| KMLSS\_BAD\_HANDLE | int | pHandle格式存在问题。 |


#### 依赖
