Detailed Description

System specific Falcon VM data.

Events, mutexes, pipes, sockets and all what's needed to run the VM in specific systems. System specific structures are in vm_sys_*.h, while implementation of this functions are in vm_sys_*.cpp.

The structures are opaque to the virtual machine, but they can be inspected by embedding applications and modules (i.e. for threading support).

Constructor & Destructor Documentation

Falcon::Sys::SystemData::SystemData

(

)

Creates the system data.

This operation is granted to succeed.

Falcon::Sys::SystemData::~SystemData

(

)

Destroys VM specific system data.

Will be performed only at ownwer vm's destruction.

Member Function Documentation

static const char* Falcon::Sys::SystemData::getSystemType

(

)

[static]

Returns overall underlying system architecture type.

It may be something as WIN or POSIX. More detailed informations about underlying systems can be retreived through modules.

Returns:

a static 7bit ASCII 0 terminated C string containing a very basic description of the underlying system overall architecture where this VM runs.

void Falcon::Sys::SystemData::interrupt

(

)

Safe interthread VM interruption request on blocking I/O.

Will work only on compliant I/O and waits.

Referenced by Falcon::VMachine::interrupt().

bool Falcon::Sys::SystemData::interrupted

(

)

const

Checks wether the VM has been interrupted in a blocking wait or I/O.

Returns:

true if interrupted.

void Falcon::Sys::SystemData::resetInterrupt

(

)

Clear interruption status.

bool Falcon::Sys::SystemData::sleep

(

numeric

seconds

)

const

Wait for a given count of seconds.

Returns:

false if interrupted.
