|
|---|
| 19 | SYNOPSIS
|
|---|
| 20 |
|
|---|
| 21 | #include <unistd.h>
|
|---|
| 22 |
|

| 25 | DESCRIPTION
|
|---|
| 26 |
|
|---|
| 27 | The fork() function shall create a new process. The new process (child process) shall be an exact copy of the calling process (parent process) except as detailed below:
|
|---|
| 28 |
|
|---|
| 29 | * The child process shall have a unique process ID.
|
|---|
| 30 | * The child process ID also shall not match any active process
|
|---|
| 31 | group ID.
|
|---|
| 32 | * The child process shall have a different parent process ID,
|
|---|
| 33 | which shall be the process ID of the calling process.
|
|---|
| 34 | * The child process shall have its own copy of the parent's file
|
|---|
| 35 | descriptors. Each of the child's file descriptors shall refer
|
|---|
| 36 | to the same open file description with the corresponding file
|
|---|
| 37 | descriptor of the parent.
