Process control

This type of services includes load, which adds a program to memory and prepares for its execution before passing control to the program itself, or execute, which runs an executable file in the context of a pre-existing process. Other operations that belong to this category are as follows:

• end and abort—the first requires the application to exit while the second forces it.
• CreateProcess, also known as fork on Unix systems or NtCreateProcess in Windows.
• Terminate process.
• Get/set process attributes.
• Wait for time, wait event, or signal event.
• Allocate and free memory.
