Constructor & Destructor Documentation

PEFLoader() [1/3]

Kernel::PEFLoader::PEFLoader ( )

explicitprivatedelete

PEFLoader() [2/3]

Kernel::PEFLoader::PEFLoader ( const VoidPtr blob )

explicit

PEF loader constructor w/ blob.

Parameters

blob	file blob.

This is a fat binary. Treat it as such.

PEFLoader() [3/3]

Kernel::PEFLoader::PEFLoader ( const Char * path )

explicit

PEF loader constructor.

Parameters

path	the filesystem path.

Note

zero here means that the FileMgr will read every container header inside the file.

This is a fat binary, treat it as such.

~PEFLoader()

Kernel::PEFLoader::~PEFLoader ( )

override

PEF destructor.

Member Function Documentation

AsString()

const Char * Kernel::PEFLoader::AsString ( )

overridevirtual

Implements Kernel::ILoader.

FindStart()

ErrorOr< VoidPtr > Kernel::PEFLoader::FindStart ( )

overridevirtual

Finds the executable entrypoint.

Returns

Implements Kernel::ILoader.

FindSymbol()

ErrorOr< VoidPtr > Kernel::PEFLoader::FindSymbol ( const Char * name, Int32 kind )

override

Finds the symbol according to it's name.

Parameters

name	name of symbol.
kind	kind of symbol we want.

fat binary check.

We set the VMAddress to nullptr, if the mapping fail here.

GetBlob()

ErrorOr< VoidPtr > Kernel::PEFLoader::GetBlob ( )

overridevirtual

Implements Kernel::ILoader.

IsLoaded()

bool Kernel::PEFLoader::IsLoaded

(

)

Tells if the executable is loaded or not.

Returns

Whether it's not bad and is cached.

MIME()

const Char * Kernel::PEFLoader::MIME ( )

overridevirtual

Implements Kernel::ILoader.

Path()

const Char * Kernel::PEFLoader::Path ( )

overridevirtual

Implements Kernel::ILoader.
