Function rb_spawn 

pub unsafe extern "C" fn rb_spawn(
    argc: c_int,
    argv: *const VALUE,
) -> pid_t

Identical to rb_f_exec, except it spawns a child process instead of replacing the current one.

@param[in] argc Number of objects in argv. @param[in] argv Command and its options to execute. @exception rb_eTypeError Invalid options e.g. non-String argv. @exception rb_eArgError Invalid options e.g. redirection cycle. @exception rb_eNotImpError Not implemented e.g. no setuid(2). @exception rb_eRuntimeError Process::UID.switch in operation. @retval -1 Child process died for some reason. @retval otherwise The ID of the born child.

@internal

This is really identical to rb_f_exec until ultimately calling the system call. Almost everything are shared among these two (and [rb_f_system].
