Function sunrise_kernel::syscalls::start_process

pub fn start_process(
    hnd: u32, 
    main_thread_prio: u32, 
    default_cpuid: u32, 
    main_thread_stacksz: usize
) -> Result<(), UserspaceError>

Start the given process on the provided CPU with the provided scheduler priority.

A stack of the given size will be allocated using the process' memory resource limit and memory pool.

The entrypoint is assumed to be the first address of the code_addr region provided in create_process(). It takes two parameters: the first is the usermode exception handling context, and should always be NULL. The second is a handle to the main thread.

Errors

• InvalidProcessorId
  • Attempted to start the process on a processor that doesn't exist on the current machine, or a processor that the process is not allowed to use.
• InvalidThreadPriority
  • Attempted to use a priority above 0x3F, or a priority that the created process is not allowed to use.
• MemoryFull
  • Provided stack size is bigger than available vmem space.
