This crate allows you to spawn a child process with ptrace enabled. It provides a single trait—CommandPtraceSpawn—that is implemented for std::process::Command, giving you access to a spawn_ptrace method.

Processes spawned this way will be stopped with SIGTRAP from their exec, so you can perform any early intervention you require prior to the process running any code and then use PTRACE_CONT to resume its execution.

Example

use std::io;
use spawn_ptrace::CommandPtraceSpawn;
use std::process::Command;

fn main() -> io::Result<()> {
   let child = Command::new("/bin/ls").spawn_ptrace()?;
   // call `ptrace(PTRACE_CONT, child.id(), ...)` to continue execution
   // do other ptrace things here...
   Ok(())
}
