CancelLazyDllUnload()

IMPORT_C TInt

CancelLazyDllUnload

(

)

CheckLibraryHash(const TDesC &, TBool)

IMPORT_C TInt	CheckLibraryHash	(	const TDesC &	aFileName,
			TBool	aValidateHash = EFalse
		)

Check if the hash for the given library exists and optionally validate it.

Parameters

const TDesC & aFileName	the same as for RLoader::LoadLibrary
TBool aValidateHash = EFalse	if ETrue this function will validate library hash if it exists. Requires fully specified aFileName.

DebugFunction(TInt, TInt, TInt, TInt)

IMPORT_C TInt	DebugFunction	(	TInt	aFunction,
			TInt	a1,
			TInt	a2,
			TInt	a3
		)

Parameters

TInt aFunction
TInt a1
TInt a2
TInt a3

Delete(const TDesC &)

IMPORT_C TInt

Delete

(

const TDesC &

aFileName

)

Ask the loader to delete a file. This function should be used instead of RFs::Delete where the supplied file may be a paged executable, although it can be used for any file. A file that is currently paged may be moved by the system, and deleted later, when the file is no longer needed. This means that using this function may not immediately release the disk space associated with the file.

capability: Tcb

capability: AllFiles

Parameters

const TDesC & aFileName

Fully-qualified filename.

GetInfo(const TDesC &, TDes8 &)

IMPORT_C TInt	GetInfo	(	const TDesC &	aFileName,
			TDes8 &	aInfoBuf
		)

Parameters

const TDesC & aFileName
TDes8 & aInfoBuf

GetInfoFromHeader(const TDesC8 &, TDes8 &)

TInt	GetInfoFromHeader	(	const TDesC8 &	aHeader,
			TDes8 &	aInfoBuf
		)

Parameters

const TDesC8 & aHeader
TDes8 & aInfoBuf

LoadDeviceDriver(const TDesC &, TInt)

TInt	LoadDeviceDriver	(	const TDesC &	aFileName,
			TInt	aDeviceType
		)

Parameters

const TDesC & aFileName
TInt aDeviceType

LoadLibrary(TInt &, const TDesC &, const TDesC &, const TUidType &, TUint32)

IMPORT_C TInt	LoadLibrary	(	TInt &	aHandle,
			const TDesC &	aFileName,
			const TDesC &	aPath,
			const TUidType &	aType,
			TUint32	aModuleVersion
		)

Parameters

TInt & aHandle
const TDesC & aFileName
const TDesC & aPath
const TUidType & aType
TUint32 aModuleVersion

LoadLocale(const TDesC &, TLibraryFunction *)

TInt	LoadLocale	(	const TDesC &	aLocaleDllName,
			TLibraryFunction *	aExportList
		)

Parameters

const TDesC & aLocaleDllName
TLibraryFunction * aExportList

LoadProcess(TInt &, const TDesC &, const TDesC &, const TUidType &, TOwnerType)

TInt	LoadProcess	(	TInt &	aHandle,
			const TDesC &	aFileName,
			const TDesC &	aCommand,
			const TUidType &	aUidType,
			TOwnerType	aType
		)

Parameters

TInt & aHandle
const TDesC & aFileName
const TDesC & aCommand
const TUidType & aUidType
TOwnerType aType

LoadProcess(TInt &, const TDesC &, const TDesC &, const TUidType &, TInt, TOwnerType)

TInt	LoadProcess	(	TInt &	aHandle,
			const TDesC &	aFileName,
			const TDesC &	aCommand,
			const TUidType &	aUidType,
			TInt	aMinStackSize,
			TOwnerType	aType
		)

Execute another process.

Parameters

TInt & aHandle
const TDesC & aFileName
const TDesC & aCommand
const TUidType & aUidType
TInt aMinStackSize
TOwnerType aType
