# KmlScadss(SPD/HPD)Get?I

获取与handle关联的整型值。

#### 接口定义

C Interface：

int KmlScadssSpdGetSI(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int64_t *value, int nvalue);

int KmlScadssSpdGetDI(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int64_t *value, int nvalue);

int KmlScadssHpdGetCI(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int64_t *value, int nvalue);

int KmlScadssHpdGetZI(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int64_t *value, int nvalue);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| pHandle | KmlScaSolverTask | 求解器句柄，pHandle不可为空指针。 | 输入 |
| param | enum KML\_SOLVER\_PARAM | KMLSS\_FILL\_IN表示填入数目。 KMLSS\_PERM表示矩阵行列顺序，暂不支持。 KMLSS\_ITER\_REF\_STEPS表示迭代优化次数，暂不支持。 | 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。 | 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为空指针。 |
| KMLSS\_BAD\_HANDLE | int | pHandle内部格式转换错误。 |
| KMLSS\_BAD\_DATA\_SIZE | int | KMLSS\_FILL\_IN数组长度nvalue设置错误。 |
| KMLSS\_INTERNAL\_ERROR | int | 内部数据返回空指针，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_scadss.h"


#### 示例

C Interface：

```
MPI_Init(NULL, NULL);
int size, rank;
MPI_Comm_size(MPI_COMM_WORLD, &size);//获取总进程数
MPI_Comm_rank(MPI_COMM_WORLD, &rank);//获取当前进程标识
int n = 8;
int ia[9] = {0, 3, 7, 9, 11, 13, 15, 16, 17};
int ja[17] = {0, 3, 4, 1, 2, 3, 5, 2, 7, 3, 6, 4, 5, 5, 7, 6, 7};
double a[17] = {1.0, 1.0, 2.0, 9.0, 2.0, 1.0, -3.0, 3.0, 2.0, 9.0, -5.0, 6.0, 1.0, 4.0, 1.0, 7.0, 2.0};
double b[8] = {4.0, 9.0, 7.0, 6.0, 9.0, 3.0, 2.0, 5.0};
double x[8];
KmlScasolverTask* matrix_handle = NULL;
int ierr = KmlScadssSpdInitDI(&matrix_handle, n, a, ja, ia, MPI_COMM_WORLD);
ierr = KmlScadssSpdAnalyzeDI(&matrix_handle);
ierr = KmlScadssSpdFactorizeDI(&matrix_handle);
int nrhs = 1;
int ldx=n, ldb=n;
ierr = KmlScadssSpdSolveDI(&matrix_handle, nrhs, x, ldx, b, ldb);
if (rank == 0) {
int64_t nnz;
ierr = KmlScadssSpdGetDI(&matrix_handle, KMLSS_FILL_IN, &nnz, 1);
printf("NNZ = %ld\n", nnz);
}
```

运行结果：
```
NNZ = 40
```
