		<description>@John,

In that case, you should use 
execv(host_program, argv); to call the program. 
The source file is updated.</description>

		<description>Not sure how to use arguments list.
If I have a program &#039;prog&#039; with arguments &#039;-pt&#039;
( ./prog -pt )

char* host_program = “prog”;
char* arglist = “pt”  (or &quot;-pt&quot;)

still invokes the program without arguments.</description>
