NAME
lfc_chmod - change access mode of a LFC directory/file in the name server
SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
int lfc_chmod (const char *path,
mode_t mode)
DESCRIPTION
lfc_chmod
sets the access permission portion of the mode of a LFC directory/file in
the name server to the bit pattern in
mode.
- path
-
specifies the logical pathname relative to the current LFC directory or
the full LFC pathname.
- mode
-
is constructed by OR'ing the bits defined in
<sys/stat.h>
under Unix or "statbits.h" under Windows/NT:
-
S_ISUID 0004000
set user ID on execution
S_ISGID 0002000
set group ID on execution
S_ISVTX 0001000
sticky bit
S_IRUSR 0000400
read by owner
S_IWUSR 0000200
write by owner
S_IXUSR 0000100
execute/search by owner
S_IRGRP 0000040
read by group
S_IWGRP 0000020
write by group
S_IXGRP 0000010
execute/search by group
S_IROTH 0000004
read by others
S_IWOTH 0000002
write by others
S_IXOTH 0000001
execute/search by others
The effective user ID of the process must match the owner of the file or
the caller must have ADMIN privilege in the Cupv database.
If a directory is writable and has the sticky bit set, files/directories within
that directory can be removed or renamed only if:
-
the effective user ID of the requestor matches the owner ID of the file or
the effective user ID of the requestor matches the owner ID of the directory or
the file is writable by the requestor or
the requestor has ADMIN privilege in the Cupv database.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
serrno
is set appropriately.
ERRORS
- EPERM
-
The effective user ID does not match the owner of the file and
the caller does not have ADMIN privilege in the Cupv database.
- ENOENT
-
The named file/directory does not exist or is a null pathname.
- EACCES
-
Search permission is denied on a component of the
path
prefix.
- EFAULT
-
path
is a NULL pointer.
- ENOTDIR
-
A component of
path
prefix is not a directory.
- ENAMETOOLONG
-
The length of
path
exceeds
CA_MAXPATHLEN
or the length of a
path
component exceeds
CA_MAXNAMELEN.
- SENOSHOST
-
Host unknown.
- SENOSSERV
-
Service unknown.
- SECOMERR
-
Communication error.
- ENSNACT
-
Name server is not running or is being shutdown.
