Member Function Documentation

CreateSentinelFile()

virtual bool FPosixOSProcessSentinel::CreateSentinelFile ( const TCHAR *  Name, const FString &  Contents  )

inlineoverridevirtual

Create the sentinel file, if possible

Returns

false if the file could not be created (because another process has it locked)

Implements IProcessSentinel.

DoesSentinelFileExistImpl()

virtual bool FPosixOSProcessSentinel::DoesSentinelFileExistImpl ( const TCHAR *  Name, FString *  OptionalOutContents  )

inlineoverrideprotectedvirtual

The actual implementation to determine if the sentinel file is exists and is valid (due to a process dying, the file may actually exist on disk, but isn't a valid file anymore, so a simple FileExists may not be good enough

Implements IProcessSentinel.
