Struct process_builder::BuiltProcess

pub struct BuiltProcess {
    pub process: Process,
    pub root_vmar: Vmar,
    pub thread: Thread,
    pub entry: usize,
    pub stack: usize,
    pub stack_base: usize,
    pub stack_vmo: Vmo,
    pub bootstrap: Channel,
    pub vdso_base: usize,
    pub elf_base: usize,
    pub elf_headers: Elf64Headers,
}

A container for a fully built but not yet started (as in, its initial thread is not yet running) process, with all related handles and metadata. Output of ProcessBuilder::build().

You can use this struct to start the process with BuiltProcess::start(), which is a simple wrapper around the zx_process_start syscall. You can optionally use the handles and information in this struct to manipulate the process or its address space before starting it, such as when creating a process in a debugger.

Fields

process: Process

The newly created process.

root_vmar: Vmar

The root VMAR for the created process.

thread: Thread

The process’s initial thread.

entry: usize

The process’s entry point.

stack: usize

The initial thread’s stack pointer.

stack_base: usize

The base address of the stack for the initial thread.

stack_vmo: Vmo

The VMO of the stack for the initial thread.

bootstrap: Channel

The bootstrap channel, to be passed to the process on start as arg1 in zx_process_start / zx::Process::start.

vdso_base: usize

The base address of the VDSO in the process’s VMAR, to be passed to the process on start as arg2 in zx_process_start / zx::Process::start.

elf_base: usize

The base address where the ELF executable, or the dynamic linker if the ELF was dynamically linked, was loaded in the process’s VMAR.

elf_headers: Elf64Headers

The ELF headers of the main module of the newly created process.

Implementations

impl BuiltProcess

pub fn start(self) -> Result<Process, ProcessBuilderError>

Start an already built process.

This is a simple wrapper around the zx_process_start syscall that consumes the handles and data in the BuiltProcess struct as needed.
