Expand description

Replaces the current process with a new process.

Legacy delimiter-based API: args and envs are single strings with entries separated by line feeds. Prefer proc_exec4 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

If the execution fails, returns an error code. Does not return otherwise.
