如果在操作系统上可用,则在 os.constants.dlopen
中导出以下常量。
有关详细信息,请参阅 dlopen(3)
。
常量 | 描述 |
---|---|
RTLD_LAZY |
执行延迟绑定。 Node.js 默认设置这个标志。 |
RTLD_NOW |
在 dlopen(3) 返回之前解析库中所有未定义的符号。 |
RTLD_GLOBAL |
库定义的符号将可用于随后加载的库的符号解析。 |
RTLD_LOCAL |
RTLDGLOBAL 的反义。
如果未指定任何标志,则这是默认行为。 |
RTLD_DEEPBIND |
使自包含库优先使用自己的符号而不是来自先前加载的库的符号。 |
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. |
