Create child process and start pipe.
- Parameters
-

| |
Open a stream connection to a pipe service.
- Parameters
-
path | to execute. |
access | mode of stream. |
args | to pass to command. |
env | to create in child process. |
buffering | size to use. |
◆ operator bool()
ucommon::pipestream::operator bool |
( |
| ) |
const |
|
inline |
See if stream connection is active.
- Returns
- true if stream is active.

◆ operator!()
bool ucommon::pipestream::operator! |
( |
| ) |
const |
|
inline |
See if stream is disconnected.
- Returns
- true if stream disconnected.

◆ overflow()
int ucommon::pipestream::overflow |
( |
int |
ch | ) |
|
|
protected |
This streambuf method is used to write the output buffer through the established pipe connection.
- Parameters
-
- Returns
- char pushed through.
◆ underflow()
int ucommon::pipestream::underflow |
( |
void |
| ) |
|
|
protected |
This streambuf method is used to load the input buffer through the established pipe connection.
- Returns
- char from get buffer, EOF if not connected.
