NAME

6       dpns_chmod  -  change  access mode of a DPNS directory/file in the name
7       server

SYNOPSIS

10       #include <sys/types.h>
11       #include "dpns_api.h"

13       int dpns_chmod (const char *path, mode_t mode)

DESCRIPTION

16       dpns_chmod sets the access permission portion of the  mode  of  a  DPNS
17       directory/file in the name server to the bit pattern in mode.
18
19       path   specifies  the  logical  pathname  relative  to the current DPNS
20              directory or the full DPNS pathname.
21
22       mode   is constructed by OR'ing the bits defined in <sys/stat.h>  under
23              Unix or  "statbits.h" under Windows/NT:
24
25              S_ISUID   0004000         set user ID on execution
26              S_ISGID   0002000         set group ID on execution
27              S_ISVTX   0001000         sticky bit
28              S_IRUSR   0000400         read by owner
29              S_IWUSR   0000200         write by owner
30              S_IXUSR   0000100         execute/search by owner
31              S_IRGRP   0000040         read by group
32              S_IWGRP   0000020         write by group
33              S_IXGRP   0000010         execute/search by group
34              S_IROTH   0000004         read by others
35              S_IWOTH   0000002         write by others
36              S_IXOTH   0000001         execute/search by others
37
38       The  effective  user ID of the process must match the owner of the file
39       or the caller must have ADMIN privilege in the  Cupv  database.   If  a
40       directory  is  writable  and  has the sticky bit set, files/directories
41       within that directory can be removed or renamed only if:
42
43              the effective user ID of the requestor matches the owner  ID  of
44              the file or
45
46              the  effective  user ID of the requestor matches the owner ID of
47              the directory or
48
49              the file is writable by the requestor or
50
51              the requestor has ADMIN privilege in the Cupv database.
52

RETURN VALUE

54       This routine returns 0 if the operation was successful  or  -1  if  the
55       operation failed. In the latter case, serrno is set appropriately.
56

ERRORS

58       EPERM        The effective user ID does not match the owner of the file
59                    and the caller does not have ADMIN privilege in  the  Cupv
60                    database.
61
62       ENOENT       The named file/directory does not exist or is a null path‐
63                    name.
64
65       EACCES       Search permission is denied on a  component  of  the  path
66                    prefix.
67
68       EFAULT       path is a NULL pointer.
69
70       ENOTDIR      A component of path prefix is not a directory.
71
72       ENAMETOOLONG The  length of path exceeds CA_MAXPATHLEN or the length of
73                    a path component exceeds CA_MAXNAMELEN.
74
75       SENOSHOST    Host unknown.
76
77       SENOSSERV    Service unknown.
78
79       SECOMERR     Communication error.
80
81       ENSNACT      Name server is not running or is being shutdown.
