Module package
controlling how `require` finds packages.
Functions
| loadlib (libname, funcname) | Dynamically links the host program with the C library `libname`. |
| seeall (module) | Sets a metatable for `module` with its `__index` field referring to the global environment, so that this module inherits values from the global environment. |
Functions
- loadlib (libname, funcname)
-
Dynamically links the host program with the C library `libname`. Inside
this library, looks for a function `funcname` and returns this function as a
C function. (So, `funcname` must follow the protocol (see `lua_CFunction`)).
This is a low-level function. It completely bypasses the package and module
system. Unlike `require`, it does not perform any path searching and does
not automatically adds extensions. `libname` must be the complete file name
of the C library, including if necessary a path and extension. `funcname`
must be the exact name exported by the C library (which may depend on the
C compiler and linker used).
This function is not supported by ANSI C. As such, it is only available
on some platforms (Windows, Linux, Mac OS X, Solaris, BSD, plus other Unix
systems that support the `dlfcn` standard).
Parameters:
- libname
- funcname
- seeall (module)
-
Sets a metatable for `module` with its `__index` field referring to the
global environment, so that this module inherits values from the global
environment. To be used as an option to function `module`.
Parameters:
- module
