+.SH NAME
+fdetach
+\(em detach a name from a STREAMS-based file descriptor (\fBSTREAMS\fP)
+.SH SYNOPSIS
+.LP
+.nf
+#include <stropts.h>
+.P
+int fdetach(const char *\fIpath\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIfdetach\fR()
+function shall detach a STREAMS-based file from the file to which
+it was attached by a previous call to
+\fIfattach\fR().
+The
+.IR path
+argument points to the pathname of the attached STREAMS file. The
+process shall have appropriate privileges or be the owner of the file.
+A successful call to
+\fIfdetach\fR()
+shall cause all pathnames that named the attached STREAMS file to again
+name the file to which the STREAMS file was attached. All subsequent
+operations on
+.IR path
+shall operate on the underlying file and not on the STREAMS file.
+.P
+All open file descriptions established while the STREAMS file was
+attached to the file referenced by
+.IR path
+shall still refer to the STREAMS file after the
+\fIfdetach\fR()
+has taken effect.
+.P
+If there are no open file descriptors or other references to the
+STREAMS file, then a successful call to
+\fIfdetach\fR()
+shall be equivalent to performing the last
+\fIclose\fR()
+on the attached file.
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIfdetach\fR()
+shall return 0; otherwise, it shall return \(mi1 and set
+.IR errno
+to indicate the error.
+.SH ERRORS
+The
+\fIfdetach\fR()
+function shall fail if:
+.TP
+.BR EACCES
+Search permission is denied on a component of the path prefix.
+.TP
+.BR EINVAL
+The
+.IR path
+argument names a file that is not currently attached.
+.TP
+.BR ELOOP
+A loop exists in symbolic links encountered during resolution of the
+.IR path
+argument.
+.TP
+.BR ENAMETOOLONG
+.br
+The length of a component of a pathname is longer than
+{NAME_MAX}.
+.TP
+.BR ENOENT
+A component of
+.IR path
+does not name an existing file or
+.IR path
+is an empty string.
+.TP
+.BR ENOTDIR
+A component of the path prefix names an existing file that is neither
+a directory nor a symbolic link to a directory, or the
+.IR path
+argument contains at least one non-\c
+<slash>
+character and ends with one or more trailing
+<slash>
+characters and the last pathname component names an existing file
+that is neither a directory nor a symbolic link to a directory.
+.TP
+.BR EPERM
+The effective user ID is not the owner of
+.IR path
+and the process does not have appropriate privileges.
+.P
+The
+\fIfdetach\fR()
+function may fail if:
+.TP
+.BR ELOOP
+More than
+{SYMLOOP_MAX}
+symbolic links were encountered during resolution of the
+.IR path
+argument.
+.TP
+.BR ENAMETOOLONG
+.br
+The length of a pathname exceeds
+{PATH_MAX},
+or pathname resolution of a symbolic link produced an intermediate
+result with a length that exceeds
+{PATH_MAX}.
+.LP

+.SH EXAMPLES
+.SS "Detaching a File"
+.P
+The following example detaches the STREAMS-based file
+.BR /tmp/named-STREAM
+from the file to which it was attached by a previous, successful call
+to
+\fIfattach\fR().
+Subsequent calls to open this file refer to the underlying file, not to
+the STREAMS file.
