Have a look at the HTTP module which uses it. argc, argv are the 
arguments of your program (argv[0] being your program), pp_env is an 
array of the environment variables, psz_cwd is the current working 
directory which should be used to start the program, p_in is a buffer 
of length i_in which will be supplied to the program as its standard 
input, and its standard output will be stored in pp_data and its 
length will be stored in pi_data.
