aclgrphProfInit
函数功能
初始化Profiling，设置Profiling参数（目前供用户设置保存性能数据文件的路径）。
函数原型
Status aclgrphProfInit(const char *profiler_path, uint32_t length)
参数说明
参数名 |
输入/输出 |
描述 |
|---|---|---|
profiler_path |
输入 |
指定保存性能数据的文件的路径，路径支持绝对路径和相对路径。 |
length |
输入 |
profiler_path的长度，单位为字节。最大长度不超过4096字节。 |
返回值
参数名 |
类型 |
描述 |
|---|---|---|
- |
Status |
SUCCESS：成功。 FAILED：失败。 ACL_ERROR_FEATURE_UNSUPPORTED：动态Profiling场景下不支持调aclgrphProfInit接口。 |
约束说明
- 不支持多次重复调用aclgrphProfInit， 并且该接口需和aclgrphProfFinalize配对使用，先调用aclgrphProfInit接口再调用aclgrphProfFinalize接口。
- 建议该接口在GEInitialize之后，AddGraph之前被调用，可采集到AddGraph时的Profiling数据。
