fdetach(3C) Standard C Library Functions fdetach(3C) NAME
fdetach - detach a name from a STREAMS-based file descriptor SYNOPSIS
#include <stropts.h> int fdetach(const char *path); DESCRIPTION
The fdetach() function detaches a STREAMS-based file from the file to which it was attached by a previous call to fattach(3C). The path argument points to the pathname of the attached STREAMS file. The process must have appropriate privileges or be the owner of the file. A successful call to fdetach() causes all pathnames that named the attached STREAMS file to again name the file to which the STREAMS file was attached. All subsequent operations on path will operate on the underlying file and not on the STREAMS file. All open file descriptions established while the STREAMS file was attached to the file referenced by path, will still refer to the STREAMS file after the fdetach() has taken effect. If there are no open file descriptors or other references to the STREAMS file, then a successful call to fdetach() has the same effect as performing the last close(2) on the attached file. RETURN VALUES
Upon successful completion, fdetach() returns 0. Otherwise, it returns -1 and sets errno to indicate the error. ERRORS
The fdetach() function will fail if: EACCES Search permission is denied on a component of the path prefix. EPERM The effective user ID is not the owner of path and the process does not have appropriate privileges. ENOTDIR A component of the path prefix is not a directory. ENOENT A component of path does not name an existing file or path is an empty string. EINVAL The path argument names a file that is not currently attached. ENAMETOOLONG The size of a pathname exceeds PATH_MAX, or a pathname component is longer than NAME_MAX while _POSIX_NO_TRUNC is in effect. ELOOP Too many symbolic links were encountered in resolving path. The fdetach() function may fail if: ENAMETOOLONG Pathname resolution of a symbolic link produced an intermediate result whose length exceeds PATH_MAX. ATTRIBUTES

fattach(3C) fattach(3C) NAME
fattach() - attach a STREAMS file descriptor to an object in the file system name space SYNOPSIS
DESCRIPTION
The function attaches the fd file descriptor to an object in the file system name space designated by path. fd specifies an open file descriptor to a STREAMS device or STREAMS-based pipe. path specifies the pathname of an existing object in the file system. A STREAMS device or pipe can be attached to more than one node in the file system name space. In other words, a STREAMS device or pipe is allowed to have several associated names. Until the STREAMS device or pipe is detached from the node (with fdetach(3C) or fdetach(1M)), all opera- tions on path will act on the STREAMS device or pipe instead of the file system object path. The stream's attributes (see the stat(2) reference page) are set according to the following scheme: o The group ID, user ID, times, and permissions are set to those of path. o The size as well as the device number are set to those of the STREAMS device or pipe designated by the fd parameter. Note that although the attributes of the STREAMS device or pipe may change (see the chmod(2) reference page), the attributes of the underlying file system object path will not be changed. o The number of links is set to 1. RETURN VALUE
Upon successful completion, the function returns a value of 0 (zero). Otherwise, it returns a value of -1, and is set to indicate the error. ERRORS
If any of the following conditions occurs, the function sets to the value that corresponds to the condition. [EACCES] Although the user is the owner of path, the user has no write permissions for it. [EBADF] The fd parameter is an invalid file descriptor. [EBUSY] The existing object specified by the path parameter is already mounted or has a file descriptor attached to it. [EFAULT] The path parameter points to a location outside of the allocated address space of the process. [EINVAL] The fd parameter does not refer to a STREAMS device or STREAMS-based pipe. [ELOOP] When path was translated, too many symbolic links were found. [ENOENT] path does not exist. [ENOTDIR] The directory portion of the path parameter does not exist. [ENAMETOOLONG] The size of a pathname component is longer than when is in effect, or the pathname length is longer than [EPERM] The current effective user ID is not the owner of the existing object specified by the path parameter.
