+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+fchown
+\(em change owner and group of a file
+.SH SYNOPSIS
+.LP
+.nf
+#include <unistd.h>
+.P
+int fchown(int \fIfildes\fP, uid_t \fIowner\fP, gid_t \fIgroup\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIfchown\fR()
+function shall be equivalent to
+\fIchown\fR()
+except that the file whose owner and group are changed is
+specified by the file descriptor
+.IR fildes .
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIfchown\fR()
+shall return 0. Otherwise, it shall return \-1 and set
+.IR errno
+to indicate the error.
+.SH ERRORS
+The
+\fIfchown\fR()
+function shall fail if:
+.TP
+.BR EBADF
+The
+.IR fildes
+argument is not an open file descriptor.
+.TP
+.BR EPERM
+The effective user ID does not match the owner of the file or the
+process does not have appropriate privileges and _POSIX_CHOWN_RESTRICTED
+indicates that such privilege is required.
+.TP
+.BR EROFS
+The file referred to by
+.IR fildes
+resides on a read-only file system.
+.P
+The
+\fIfchown\fR()
+function may fail if:
+.TP
+.BR EINVAL
+The owner or group ID is not a value supported by the implementation.
+The
+.IR fildes
+argument refers to a pipe or socket
+or an
+\fIfattach\fR()-ed
+STREAM
+and the implementation disallows execution of
+\fIfchown\fR()
+on a pipe.
+.TP
+.BR EIO
+A physical I/O error has occurred.
+.TP
+.BR EINTR
+The
+\fIfchown\fR()
+function was interrupted by a signal which was caught.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+.SS "Changing the Current Owner of a File"
+.P
+The following example shows how to change the owner of a file named
+.BR /home/cnd/mod1
+to ``jones'' and the group to ``cnd''.
+.P
+The numeric value for the user ID is obtained by extracting the user ID
+from the user database entry associated with ``jones''. Similarly, the
+numeric value for the group ID is obtained by extracting the group ID
+from the group database entry associated with ``cnd''. This example
+assumes the calling program has appropriate privileges.
