dlopen Constants
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，请参阅dlopen（3）信息。
| 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. |
If available on the operating system, the following constants
are exported in os.constants.dlopen. See dlopen(3) for detailed
