获取当前文件路径 - LogGetCurrentFilePath

函数简介

获取日志实例当前正在使用的日志文件路径。

接口名称

LogGetCurrentFilePath

DLL调用

const char* LogGetCurrentFilePath(int64_t instance, int64_t loggerHandle);

参数说明

参数名	类型	说明
instance	长整数型	OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
loggerHandle	长整数型	日志实例句柄（0 表示默认实例）。

示例

配置路径并写日志后，打印当前实际文件路径。

返回值

返回值	说明
（返回值）	当前文件路径（字符串），失败返回空字符串或 NULL。返回的字符串指针需要调用 FreeStringPtr 接口释放内存。

注意事项

项目	说明
释放内存	返回的字符串指针需要调用 FreeStringPtr 接口释放内存。
如果日志系统未初始化	如果日志系统未初始化，返回空字符串或 NULL。
路径	返回的是完整的绝对路径。
路径	文件路径会随着日志分割而变化。
