Function rb_waitpid

pub unsafe extern "C" fn rb_waitpid(
    pid: pid_t,
    status: *mut c_int,
    flags: c_int,
) -> pid_t

Waits for a process, with releasing GVL.

@param[in] pid Process ID. @param[out] status The wait status is filled back. @param[in] flags Wait options. @retval -1 System call failed, errno set. @retval 0 WNOHANG but no waitable children. @retval otherwise A process ID that was wait()-ed. @post Upon successful return status is updated to have the process’ status. @note status can be NULL. @note The arguments are passed through to underlying system call(s). Can have special meanings. For instance passing ([rb_pid_t]-1 to pid means it waits for any processes, under POSIX-compliant situations.
