46 * The following structure is found at the top of the user stack of each
\r
47 * user process. The ps program uses it to locate argv and environment
\r
48 * strings. Programs that wish ps to display other information may modify
\r
49 * it; normally ps_argvstr points to the text for argv[0], and ps_nargvstr
\r
50 * is the same as the program's argc. The fields ps_envstr and ps_nenvstr
\r
51 * are the equivalent for the environment.
