SYNOPSIS

12       int fattach(int fildes, const char *path);

DESCRIPTION

16       The fattach() function attaches a STREAMS- or doors-based file descrip‐
17       tor to an object in the file system name space, effectively associating
18       a name with fildes. The fildes argument  must  be  a  valid  open  file
19       descriptor representing a STREAMS or doors file. The path argument is a
20       path name of an existing object and  the  user  must  have  appropriate
21       privileges  or be the owner of the file and have write permissions. All
22       subsequent operations on path will operate on the STREAMS or doors file
23       until  the  STREAMS or doors file is detached from the node. The fildes
24       argument can be attached to more than one path, that is,  a  stream  or
25       door can have several names associated with it.
26
27
28       The  attributes of the named stream or door (see stat(2)), are initial‐
29       ized as follows: the permissions, user ID, group ID, and times are  set
30       to  those  of  path,  the number of links is set to 1, and the size and
31       device identifier are set to those of the streams or doors device asso‐
32       ciated  with  fildes. If any attributes of the named stream or door are
33       subsequently changed  (for example, chmod(2)), the  attributes  of  the
34       underlying object are not affected.
35

RETURN VALUES

37       Upon  successful completion, fattach() returns 0.  Otherwise it returns
38       −1 and sets  errno to indicate an error.

ERRORS

41       The fattach() function will fail if:
42
43       EACCES          The user is the owner of path but does not  have  write
44                       permissions on path or fildes is locked.
45
46
47       EBADF           The  fildes  argument is not a valid open file descrip‐
48                       tor.
49
50
51       EBUSY           The path argument is currently a mount point or  has  a
52                       STREAMS or doors file descriptor attached to it.
53
54
55       EINVAL          The  path  argument  is  a  file  in a remotely mounted
56                       directory.
57
58
59       EINVAL          The fildes argument does not  represent  a  STREAMS  or
60                       doors file.
61
62
63       ELOOP           Too many symbolic links were encountered in translating
64                       path.
65
66
67       ENAMETOOLONG    The size of path exceeds {PATH_MAX}, or  the  component
68                       of   a  path  name  is  longer  than  {NAME_MAX}  while
69                       {_POSIX_NO_TRUNC} is in effect.
70
71
72       ENOENT          The path argument does not exist.
73
74
75       ENOTDIR         A component of a path prefix is not a directory.
76
77
78       EPERM           The effective user ID is not the owner  of  path  or  a
79                       user with the appropriate privileges.
