Function trace 

pub fn trace(
    cmd: Vec<&str>,
    conf: &mut TracerConf,
    runtime_conf: &RuntimeConf<'_>,
) -> Result<ProcessList, String>

Main syswall tracing function: allows a child process to be executed and traced by syswall

When called, the current process will fork and the child will execute cmd. The parent will then enter the trace loop which processes the syscalls for the child (tracee) process. When the child process terminates, this function will return.

Arguments

• cmd: command and arguments used for running the child process (e.g. [“ls”, “-l”])
• conf: TracerConf instance which will be used and modified during the trace
• runtime_conf: RuntimeConf instance which provides details of the runtime interface

Returns

Upon success, returns an Ok(ProcessList) containing the states of all tracee processes.

Example

use syswall::trace;
use syswall::tracer_conf::{RuntimeConf, TracerConf};

let cmd = vec!["ls", "-l"];
let mut conf = TracerConf::default();
let runtime_conf = RuntimeConf::default();
if let Ok(process_states) = trace(cmd, &mut conf, &runtime_conf) {
    // Handle final process status reports
}
