Expand description

Spawns a new sub-process (posix-spawn style).

Legacy delimiter-based API: args and envs are single strings with entries separated by line feeds. Prefer proc_spawn3 for proper string lists.

§Parameters

  • name - Name of the process to be spawned
  • args - List of the arguments to pass the process (entries are separated by line feeds)
  • envs - List of the environment variables to pass process

§Return

On success, writes the child PID to ret and returns Errno::Success. On failure, returns an error code.
