42 * The following structure is found at the top of the user stack of each
43 * user process. The ps program uses it to locate argv and environment
44 * strings. Programs that wish ps to display other information may modify
45 * it; normally ps_argvstr points to the argv vector, and ps_nargvstr
46 * is the same as the program's argc. The fields ps_envstr and ps_nenvstr
47 * are the equivalent for the environment.
50 char **ps_argvstr; /* first of 0 or more argument strings */
51 unsigned int ps_nargvstr; /* the number of argument strings */
52 char **ps_envstr; /* first of 0 or more environment strings */
53 unsigned int ps_nenvstr; /* the number of environment strings */
57 * Address of ps_strings structure (in user space).
