   OSProcessC   
 
OSProcess handle.

Source file:Ravl/OS/Exec/OSProcess.hh
User Level:Normal
Library:RavlOS
In Scope:RavlN

Parent Classes: Derived Classes: Methods:
OSProcessC()
Default constructor.
Creates an invalid handle.

OSProcessC(int npid)
Default constructor.

bool Signal(IntT signo)
Send a signal to the process.

bool Kill(bool hard = false)
Kill the child process.
The process should die sometime after this call though it may not be immediatly.

int Pid() const
Get process id.

UIntT Hash() const
Hash on pid.

bool operator ==(const OSProcessC & oth) const
Compair two processes.

static int WaitForChild(int & status)
Wait for change in state of a child process.
returns PID of child that's changed state. -1 = Call interupted. 0 = No children.



OSProcessC(OSProcessBodyC & bod)
Body constructor.

OSProcessBodyC & Body()
Access body.

const OSProcessBodyC & Body() const
Access body.

UIntT MemorySize()
Get the amount of memory this process is using.
Returns 0 on failure. 1 if special Will return ((UIntT) -1) if process size is bigger than 4Gb.

bool SigStop()
Stop this process. (Like Ctrl-z)

bool SigContinue()
Start this process.
Restart the this process after a stop.

#include "Ravl/RefCounter.hh"
const RCHandleC<OSProcessBodyC> & operator =(const RCHandleC<OSProcessBodyC> & oth)
Assign handle.

RCHandleC<OSProcessBodyC> DeepCopy(UIntT levels = ((UIntT))) const
Do a deep copy of the object.

bool operator ==(const RCHandleC<OSProcessBodyC> & oth) const
Are handles to the same object ?

bool operator !=(const RCHandleC<OSProcessBodyC> & oth) const
Are handles to different objects ?

UIntT Hash() const
Default hash function.
This hashes on the address of the body.

bool IsValid() const
Test if this is a valid handle.

void Invalidate()
Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const
Is handle of given type ?

void CheckHandleType(const DT & dummy) const
Check handle type. Throw an expception if not.

OSProcessBodyC & Body()
Access body of object.

const OSProcessBodyC & Body() const
Constant access to body of object.

UIntT References() const
Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<OSProcessBodyC> & obj)

istream & operator >>(istream & strm,RCHandleC<OSProcessBodyC> & obj)
