# KmlDssSymGet?IL

获取与handle关联的长整型值。

#### 接口定义

C Interface：

int KmlDssSymGetSIL(KmlSolverTask **pHandle, enum KmlSolverParam param, int64_t *value, int nvalue);

int KmlDssSymGetDIL(KmlSolverTask **pHandle, enum KmlSolverParam param, int64_t *value, int nvalue);

int KmlDssSymGetCIL(KmlSolverTask **pHandle, enum KmlSolverParam param, int64_t *value, int nvalue);

int KmlDssSymGetZIL(KmlSolverTask **pHandle, enum KmlSolverParam param, int64_t *value, int nvalue);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| pHandle | KmlSolverTask \*\* | 求解器句柄，pHandle不可为空指针。 | 输入 |
| param | enum KmlSolverParam | 当前仅支持KMLSS\_FILL\_IN，表示填入数目。 | 输入 |
| value | int64\_t \* | 直接求解相关参数数组。 | 输出 |
| nvalue | int | value数组元素个数，目前要求为1。 | 输入 |


#### 返回值

| 返回值 | 类型 | 描述 |
| --- | --- | --- |
| KMLSS\_NO\_ERROR | int | 正常执行。 |
| KMLSS\_NULL\_ARGUMENT | int | pHandle或data为空指针。 |
| KMLSS\_BAD\_HANDLE | int | pHandle格式存在问题。 |
| KMLSS\_BAD\_DATA\_SIZE | int | 用户设定的value数组长度nvalue不合理。 |
| KMLSS\_INTERNAL\_ERROR | int | pHandle状态异常，KMLSS\_FILL\_IN获取失败。 |
| KMLSS\_BAD\_SELECTOR | int | 用户的KML\_SOLVER\_PARAM输入当前不支持，或在求解过程中不存在。 |


#### 依赖

#include "kml_dss.h"或#include "kml_solver.h"


#### 示例

C Interface：

```
int n = 8;
int ia[9] = {0, 2, 4, 6, 7, 8, 9, 10, 11};
int ja[11] = {0, 7, 1, 6, 2, 5, 3, 4, 5, 6, 7};
double a[11] = {1.0, 2.0, -2.0, 3.0, 3.0, 4.0, -4.0, 5.0, -6.0, 7.0, 8.0};

double b[8] = {3.0, 1.0, 7.0, -4.0, 5.0, -2.0, 10.0, 10.0};
double x[8];
int nrhs = 1;
int ldx = n, ldb = n;

KmlSolverTask *handle;
int ierr = KmlDssSymInitDI(&handle, n, a, ja, ia);
if (ierr != 0) {
        printf("\nERROR in KmlDssSymInitDI: %d", ierr);
}
ierr = KmlDssSymAnalyzeDI(&handle);
if (ierr != 0) {
        printf("\nERROR in KmlDssSymAnalyzeDI: %d", ierr);
}
ierr = KmlDssSymFactorizeDI(&handle);
if (ierr != 0) {
        printf("\nERROR in KmlDssSymFactorizeDI: %d", ierr);
}
ierr = KmlDssSymSolveDI(&handle, nrhs, x, ldx, b, ldb);
if (ierr != 0) {
        printf("\nERROR in KmlDssSymSolveDI: %d", ierr);
}

int64_t nnz;
ierr = KmlDssSymGetDIL(&handle, KMLSS_FILL_IN, &nnz, 1);
if (ierr != 0) {
        printf("\nERROR in KmlDssSymGetDIL: %d", ierr);
}
printf("NNZ = %d\n", nnz);
```

运行结果：```
NNZ = 32
```
