From 5fefd233769a56caefdb2ffecaa9fb8b9ec6db86 Mon Sep 17 00:00:00 2001 From: user Date: Thu, 16 Jul 2026 12:49:19 +0200 Subject: fs rewrite stage 3: nested directories, paths, cwd (cd/mkdir/ls) - directories generalized: dir_find/dir_add/dir_remove take any dir inode; every dir carries '.'/'..'. Path resolution (resolve / resolve_parent) walks absolute or cwd-relative paths; open/mkdir/chdir/remove/opendir take paths. - per-process cwd: PROC_CWD in the PCB (root by default, inherited on fork); sys_chdir sets it, sys_opendir points ls at any directory. - shell: 'cd' builtin + cwd-aware prompt; 'mkdir'/'ls ' tools; 'exit'/'quit' and EOF call poweroff() (clean shutdown via the $ED opcode -> reliable save). - three HL/buffer-clobber bugs fixed along the way: resolve didn't preserve the path cursor across dir_find; cur_cwd clobbered HL; resolve_parent set the final name before resolve() overwrote wFsNameBuf (now copied after). - verified: nested mkdir/cd/save, multi-level paths (cat docs/sub/b), and the whole tree persists across a reboot. - README: document directories + the poweroff opcode. --- c/mkdir.c | 8 ++++++++ 1 file changed, 8 insertions(+) create mode 100644 c/mkdir.c (limited to 'c/mkdir.c') diff --git a/c/mkdir.c b/c/mkdir.c new file mode 100644 index 0000000..c907518 --- /dev/null +++ b/c/mkdir.c @@ -0,0 +1,8 @@ +#include "gbos.h" +/* mkdir : create a directory. */ +void main(void) { + char *argv[4]; + unsigned char argc = argv_parse(argv, 4); + if (argc < 1) { puts("usage: mkdir "); nl(); return; } + if (mkdir(argv[0])) { puts("mkdir: failed"); nl(); } +} -- cgit v1.3.1-sl0p
