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