PtyProcess Class Reference
#include <process.h>
Inheritance diagram for PtyProcess:

Detailed Description
Synchronous communication with tty programs.PtyProcess provides synchronous communication with tty based programs. The communications channel used is a pseudo tty (as opposed to a pipe) This means that programs which require a terminal will work.

Member Function Documentation
|
Enables/disables local echo on the pseudo tty.
Definition at line 379 of file process.cpp. |
|
Forks off and execute a command. The command's standard in and output are connected to the pseudo tty. They are accessible with readLine and writeLine.
Definition at line 261 of file process.cpp. |
|
Returns the filedescriptor of the process.
|
|
Returns the pid of the process.
|
|
Reads a line from the program's standard out. Depending on the block parameter, this call blocks until a single, full line is read.
Definition at line 166 of file process.cpp. |
|
Set additinal environment variables.
Definition at line 150 of file process.cpp. |
|
Overwrites the password as soon as it is used. Relevant only to some subclasses. |
|
Sets the exit string. If a line of program output matches this, waitForChild() will terminate the program and return. |
|
Enables/disables terminal output. Relevant only to some subclasses. |
|
Puts back a line of input.
Definition at line 248 of file process.cpp. |
|
Waits for the child to exit. See also setExitString. Definition at line 415 of file process.cpp. |
|
Waits until the pty has cleared the ECHO flag. This is useful when programs write a password prompt before they disable ECHO. Disabling it might flush any input that was written. Definition at line 341 of file process.cpp. |
|
Writes a line of text to the program's standard in.
Definition at line 239 of file process.cpp. |
