Protected Member Functions

	Standard C++11 thread is automatically launched, so we cannot control the starting time. Calling this function guarantees that E_Main thread is successfully launched.
virtual int	E_Syscall (const SystemCallInterface::SystemCallParameter &param) final
	This is equivalent to INT 0x80 instruction of Linux. This function may be blocked if the system call is blocking call.

E_Syscall()

int E::SystemCallApplication::E_Syscall ( const SystemCallInterface::SystemCallParameter &  param )

finalprotectedvirtual

This is equivalent to INT 0x80 instruction of Linux. This function may be blocked if the system call is blocking call.

Parameters
