dlopen 常量
如果在操作系统上可用，则以下常量在 os.constants.dlopen 中导出。
有关详细信息，请参见 dlopen(3) 信息。
| 常量 | 描述 |
|---|---|
RTLD_LAZY |
执行延迟绑定。 Node.js 默认设置此标志。 |
RTLD_NOW |
在 dlopen(3) 返回之前解析库中的所有未定义符号。 |
RTLD_GLOBAL |
库定义的符号将可用于后续加载的库的符号解析。 |
RTLD_LOCAL |
与 RTLD_GLOBAL 相反。 如果未指定任何标志，则这是默认行为。 |
RTLD_DEEPBIND |
使一个独立的库使用自己的符号，而不是先前加载的库中的符号。 |
If available on the operating system, the following constants
are exported in os.constants.dlopen. See dlopen(3) for detailed
information.
| Constant | Description |
|---|---|
RTLD_LAZY |
Perform lazy binding. Node.js sets this flag by default. |
RTLD_NOW |
Resolve all undefined symbols in the library before dlopen(3) returns. |
RTLD_GLOBAL |
Symbols defined by the library will be made available for symbol resolution of subsequently loaded libraries. |
RTLD_LOCAL |
The converse of RTLD_GLOBAL. This is the default behavior
if neither flag is specified. |
RTLD_DEEPBIND |
Make a self-contained library use its own symbols in preference to symbols from previously loaded libraries. |
