.. c:function:: int uv_dlopen(const char* filename, uv_lib_t* lib)
|
||
|
|
|
||
|
|
Opens a shared library. The filename is in utf-8. Returns 0 on success and
|
||
|
|
-1 on error. Call :c:func:`uv_dlerror` to get the error message.

|
||
|
|
|
||

.. c:function:: int uv_dlsym(uv_lib_t* lib, const char* name, void** ptr)
|
||
|
|
|
||
|
|
Retrieves a data pointer from a dynamic library. It is legal for a symbol
|
||
|
|
to map to NULL. Returns 0 on success and -1 if the symbol was not found.

|
|
||
|
|
.. c:function:: const char* uv_dlerror(const uv_lib_t* lib)
