This syscall allows a parent process to disown a child process, setting its parent PID to 0. Unparented processes are automatically reaped by the kernel upon exit, and no sys$waitid() is required. This will make it much nicer to do spawn-and-forget which is common in the GUI environment.

## Name
|
|
|
|
disown - disown a child process
|
|
|
|
## Synopsis
|
|
|
|
```**c++
|
|
#include <serenity.h>
|
|
|
|
int disown(pid_t pid);
|
|
```
|
|
|
|
## Description
|
|
|
|
`disown()` unparents a child process of the calling process. The child's parent PID is set to zero, which allows the kernel to automatically reap it upon death.
|
|
|
|
## Pledge
|
|
|
|
In pledged programs, the `proc` promise is required for this system call.
|
|
|
|
## Errors
|
|
|
|
* `ESRCH`: No process with PID `pid` was found.
|
|
* `ECHILD`: The target process is not a child of the calling process.
