NAME

       fattach - attach a STREAMS- or doors-based file descriptor to an object in the file system name space

SYNOPSIS

       #include <stropts.h>

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

DESCRIPTION

       The fattach() function attaches a STREAMS- or doors-based file descriptor to an object in the file system name space, effectively associat-
       ing a name with fildes. The fildes argument must be a valid open file descriptor representing a STREAMS or doors file. The path argument is
       a path name of an existing object and the user must have appropriate privileges or be the owner of the file and have write permissions. All
       subsequent operations on path will operate on the STREAMS or doors file until the STREAMS or doors file is  detached  from  the	node.  The
       fildes argument can be attached to more than one path, that is, a stream or door can have several names associated with it.

       The attributes of the named stream or door (see stat(2)), are initialized as follows: the permissions, user ID, group ID, and times are set
       to those of path, the number of links is set to 1, and the size and device identifier are set to those of the streams or doors device asso-
       ciated  with fildes. If any attributes of the named stream or door are subsequently changed  (for example, chmod(2)), the attributes of the
       underlying object are not affected.

RETURN VALUES

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

ERRORS

       The fattach() function will fail if:

       EACCES	       The user is the owner of path but does not have write permissions on path or fildes is locked.

       EBADF	       The fildes argument is not a valid open file descriptor.

       EBUSY	       The path argument is currently a mount point or has a STREAMS or doors file descriptor attached to it.

       EINVAL	       The path argument is a file in a remotely mounted directory.

       EINVAL	       The fildes argument does not represent a STREAMS or doors file.

       ELOOP	       Too many symbolic links were encountered in translating path.

       ENAMETOOLONG    The size of path exceeds {PATH_MAX}, or the component of a path name is longer than {NAME_MAX} while  {_POSIX_NO_TRUNC}	is
		       in effect.

       ENOENT	       The path argument does not exist.

       ENOTDIR	       A component of a path prefix is not a directory.

       EPERM	       The effective user ID is not the owner of path or a user with the appropriate privileges.
