Method of performing kernel task upon initial execution of process at user level

摘要

An embodiment of a method of performing a kernel level task upon initial execution of a child process at a user level begins with setting an instruction pointer for an initial child process instruction to an instruction to enter a kernel level. The method continues with beginning the child process which places a return value in a register for the child process and which causes the child process to enter the kernel level. The method concludes with executing a system call having a system call number of the return value. The system call comprises the kernel level task.
