simSubprocess.execAsync
|
Description
|
Execute a subprocess without waiting for termination. |
| Lua synopsis |
string handle=simSubprocess.execAsync(string programPath, string[] args, exec_opts opts={})
|
| Lua parameters |
programPath (string): Program path.
args (table of string): Program arguments.
opts (exec_opts, default: {}): Options. see exec_opts
|
| Lua return values |
handle (string) |

simSubprocess.getpid
|
Description
|
Get the process identifier (OS-dependent). |
| Lua synopsis |
long pid=simSubprocess.getpid(string handle)
|
| Lua parameters |
handle (string) |
| Lua return values |
pid (long) |
| Python synopsis |
long pid=simSubprocess.getpid(string handle)
|
simSubprocess.isRunning
|
Description
|
Check wether a subprocess previously launched with simSubprocess.execAsync is running. |
| Lua synopsis |
bool running=simSubprocess.isRunning(string handle)
|
| Lua parameters |
handle (string) |
| Lua return values |
running (bool) |

simSubprocess.kill
|
Description
|
Forcefully terminate a subprocess previously launched with simSubprocess.execAsync. |

exitCode (int) |
| Python synopsis |
int exitCode=simSubprocess.kill(string handle)
|
simSubprocess.wait
|
Description
|
Wait for termination of a subprocess previously launched with simSubprocess.execAsync. If subprocess terminates, the exit code is returned. |
| Lua synopsis |
int exitCode=simSubprocess.wait(string handle, float timeout=5)
|
| Lua parameters |
handle (string)
timeout (float, default: 5)

Data structures
Data structures are used to pass complex data around. Create data structures in Lua in the form of a map, e.g.: {line_size=3, add_to_legend=false, selectable=true}
exec_opts

|
|
| Fields |
useSearchPath (bool, default: true): Resolve program name searching in PATH entries.
