# kupl_egroup_reset

重置egroup至创建时的状态。

#### 接口定义

void kupl_egroup_reset(kupl_egroup_h group);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| group | kupl\_egroup\_h | 需要重置的egroup对象，egroup为nullptr时，默认barrier全局 | 输入/输出 |


#### 示例

```
#include <stdio.h>  
#include "kupl.h"  

int main()  
{  
    int executor_num = kupl_get_num_executors();  
    int n1 = executor_num/2;  
    int n2 = executor_num - executor_num/2; 
    int executors1[n1], executors2[n2];  
    for (int i =0; i < n1; i++) { 
        executors1[i] = i; 
    }  
    for (int i =0; i < n2; i++) { 
        executors2[i] = i + n1; 
    }  
    kupl_egroup_h egroup1 = kupl_egroup_create(executors1, n1);  
    kupl_egroup_h egroup2 = kupl_egroup_create(executors2, n2);  
    n1 = kupl_egroup_borrow(egroup1, egroup2);  
    kupl_egroup_reset(egroup1);  
    kupl_egroup_reset(egroup2); 
    kupl_egroup_destroy(egroup1);  
    kupl_egroup_destroy(egroup2);  
    return 0;  
}
```

上述示例演示了创建egroup1与egroup2后，通过kupl_egroup_borrow函数改变egroup1与egroup2，最终通过kupl_egroup_reset函数将egroup1与egroup2都重置为创建时的状态。
