设置文件分割模式 - LogSetRotationMode
函数简介
设置日志文件的分割模式,支持按大小、按日期、按小时等多种方式分割日志文件。
接口名称
LogSetRotationModeDLL调用
c
int32_t LogSetRotationMode(int64_t instance, int64_t loggerHandle, int32_t rotationMode);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)。 |
| rotationMode | 整数型 | 分割模式(可位或组合),见 LogRotationMode 枚举。 |
LogRotationMode 枚举值
| 枚举值 | 值 | 说明 |
|---|---|---|
| OLA_LOG_ROTATION_NONE | 0 | 不分割(单文件,不推荐) |
| OLA_LOG_ROTATION_SIZE | 1 | 按大小分割(默认启用) |
| OLA_LOG_ROTATION_DAILY | 2 | 每日分割 |
| OLA_LOG_ROTATION_HOURLY | 4 | 每小时分割 |
位运算组合示例
将需要的分割模式 按位或(|)相加 后传入 rotationMode(满足任一条件即触发分割):
csharp
// 按大小 + 每日分割
int rotationMode = 1 | 2; // OLA_LOG_ROTATION_SIZE | OLA_LOG_ROTATION_DAILY
ola.LogSetRotationMode(0, rotationMode);
// 三种模式全部启用
int allModes = 1 | 2 | 4; // 7
ola.LogSetRotationMode(0, allModes);cpp
// 按大小 + 每小时分割
int rotationMode = 1 | 4; // 5
ola.LogSetRotationMode(0, rotationMode);python
# 仅按大小分割(默认)
ola.LogSetRotationMode(0, 1)
# 按大小 + 每日分割
ola.LogSetRotationMode(0, 1 | 2)示例
Rotation:SIZE=1 DAILY=2 HOURLY=4。示例:1|2(按大小+每日),配合 MaxFileSize 与 {index}。

| 返回值 | 说明 |
|---|---|
1 | 成功。 |
0 | 失败。 |
注意事项
| 项目 | 说明 |
|---|---|
| 默认值 | OLA_LOG_ROTATION_SIZE (1) - 仅按大小分割。 |
| 可以使用位或运算(` | `)组合多种模式 |
| LogSetMaxFileSize | 按大小分割的阈值通过 LogSetMaxFileSize 设置(默认 100MB)。 |
| LogSetMaxFiles | 分割后的旧文件数量通过 LogSetMaxFiles 控制(默认保留 10 个)。 |
| 修改后立即生效 | 修改后立即生效,如果日志系统已初始化,会自动重新初始化。 |
| 组合使用时 | 组合使用时,满足任一条件都会触发分割。 |
