## Name
module\_load - load a kernel module
## Synopsis
```**c++
#include <serenity.h>
int module_load(const char* path, size_t path_length);
```
## Description
`module_load()` will load a kernel module from an ELF object file given its
path in the filesystem.
## Return value
If the module is successfully loaded, `module_load()` returns 0. Otherwise, it
returns -1 and sets `errno` to describe the error.
## Errors
* `EPERM`: The calling process does not have superuser permissions.
* `EFAULT`: `path` pointed to memory that was not accessible for the caller.
* `ENOEXEC`: The specified file could not be parsed as an ELF object.
* `ENOENT`: One or more symbols referred to by the module could not be resolved.
* `EINVAL`: The module had no `.text` section, or didn't export a `module_init` function.
* `EEXIST`: A module with the same name was already loaded.
