.Nm lchmod
.Nd change mode of file
.Sh SYNOPSIS
.In sys/stat.h
.In unistd.h
.Ft int
.Fn lchmod "const char *path" "mode_t flags"
.Sh DESCRIPTION
The function
.Fn lchmod
sets the file permission bits of the file specified by the pathname
.Fa path
to
.Fa mode .
See
.Xr chmod 2
for the values of the
.Fa flags .
.Pp
The
.Fn lchmod
call is like
.Fn chmod
except when the named file is a symbolic link,
in which case
.Fn lchmod
will change the flags of the link itself,
rather than the file it points to.
.Sh NOTE
Instead of being a system call,
.Fn lchmod
is emulated using
.Xr setattrlist 2 .
Not all file systems support
.Xr setattrlist 2 .
.Sh RETURN VALUES
Upon successful completion, a value of 0 is returned.
Otherwise, -1 is returned and the global variable
.Va errno
is set to indicate the error.
.Sh ERRORS
The
.Fn lchmod
call may return the same errors as
.Xr chmod 2
and
.Xr setattrlist 2 .
