From 56e5d28c812ad3851c02d20df93cd6f00ada64bb Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Thu, 10 Aug 2000 19:47:55 +0000 Subject: More stuff. Down to only 43 missing functions before BusyBox will link. Fixed socket stuff so it doesn't pull in kernel headers and stubbed out fork and clone. A few other header file cleanups. -Erik --- include/unistd.h | 74 ++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 72 insertions(+), 2 deletions(-) (limited to 'include/unistd.h') diff --git a/include/unistd.h b/include/unistd.h index 57a203dfd..6c2d1cece 100644 --- a/include/unistd.h +++ b/include/unistd.h @@ -65,13 +65,71 @@ extern char * mktemp __P ((char * __template)); extern int _clone __P ((int (*fn)(void *arg), void *child_stack, int flags, void *arg)); +/* Return the current machine's Internet number. */ +extern long int gethostid __P ((void)); -/* Make PATH be the root directory (the starting point for absolute paths). +/* Put the name of the current host in no more than LEN bytes of NAME. + The result is null-terminated if LEN is large enough for the full + name and the terminator. */ +extern int gethostname __P ((char *__name, size_t __len)); + +/* Set the name of the current host to NAME, which is LEN bytes long.
