|

| 45 | * An instance of a subclass of <code>Process</code> is created by the
|
|---|
| 46 | * <code>Runtime.exec</code> methods. Methods in <code>Process</code>
|
|---|
| 47 | * provide a means to send input to a process, obtain the output from a
|
|---|
| 48 | * subprocess, destroy a subprocess, obtain the exit value from a
|
|---|
| 49 | * subprocess, and wait for a subprocess to complete.
|
|---|
| 50 | *
|
|---|
| 51 | * <p>This is dependent on the platform, and some processes (like native
|
|---|
| 52 | * windowing processes, 16-bit processes in Windows, or shell scripts) may
|
|---|
| 53 | * be limited in functionality. Because some platforms have limited buffers
|
|---|
| 54 | * between processes, you may need to provide input and read output to prevent
|
|---|
| 55 | * the process from blocking, or even deadlocking.
|
|---|
| 56 | *
|
|---|
| 57 | * <p>Even if all references to this object disapper, the process continues
|
|---|
| 58 | * to execute to completion. There are no guarantees that the
|
|---|
| 59 | * subprocess execute asynchronously or concurrently with the process which
|
|---|
| 60 | * owns this object.
