NAME

fdetach - Detaches a file name from a STREAMS-based file descriptor  

LIBRARY

Standard C Library (libc.so, libc.a)  

SYNOPSIS

#include <stropts.h>

int fdetach(        const char *path);
 

STANDARDS

Interfaces documented on this reference page conform to industry standards as follows:

fdetach(): XPG4-UNIX

Refer to the standards(5) reference page for more information about industry standards and associated tags.  

PARAMETERS

Specifies the pathname of an existing object in the file system name space that was previously attached (see the fattach() reference page).  

DESCRIPTION

The fdetach() function separates (detaches) a STREAMS-based file descriptor from a name in the file system designated by path. As a result of this operation, the node's status and permissions return to the state prior to the file attaching to the node. Any later operations on path will affect only the file system node and not the attached file. The user must either have the proper permissions to allow access to the file, or own the file.  

RETURN VALUES

Upon successful completion, the fdetach() function returns a value of 0 (zero). Otherwise, it returns a value of -1 is returned, and errno is set to indicate the error.  

ERRORS

If any of the following conditions occurs, the fdetach() function sets errno to the value that corresponds to the condition. The user is not the owner of the file or does not have the correct permissions to access the file. [Digital]  There is an active reference to a file located on the file system. [Digital]  The path parameter points outside the process's allocated address space. The object pointed to by the path parameter is not attached to a file. When path was translated, too many symbolic links were found. The path parameter points to a pathname that does not exist. The directory portion of the path parameter does not exist. The size of a pathname component is longer than [NAME_MAX] when [_POSIX_NO_TRUNC] is in effect, the pathname length is longer than [PATH_MAX], or the length of the intermediate result of a pathname resolution of a symbolic link is longer than PATH_MAX. The current effective user ID is not the owner of the existing object specified by the path parameter, or the current effective user ID does not specify a user with the correct privileges.  

RESTRICTIONS

[Digital]  The fdetach() function requires that the FFM_FS kernel option be configured. See System Administration for information on configuring kernel options.
