Cmdline returns the command line arguments of the process as a string with each argument separated by 0x20 ascii character.

func (*Process) CmdlineSlice

func (p *Process) CmdlineSlice() ([]string, error)

CmdlineSlice returns the command line arguments of the process as a slice with each element being an argument.
