ENOENT means "no such file or directory", not "no such symbol". Return EINVAL instead, as we already do in other cases.

## 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.
|
|
* `EINVAL`: One or more symbols referred to by the module could not be resolved, or the module had no `.text` section, or didn't export a `module_init` function.
|
|
* `EEXIST`: A module with the same name was already loaded.
