.Sh SYNOPSIS
.Fd #include <unistd.h>
.Ft char *
.Fn getflags "u_long flags" "char *def"
.Ft int
.Fn setflags "char **stringp" "u_long *setp" "u_long *clrp"
.Sh DESCRIPTION
The
.Fn getflags
function returns a comma separated string of the file flags represented by
.Fa flags .
If no flags are set the string
.Fa def
is returned instead.
.Pp
The
.Fn setflags
function takes a string of file flags, as described in
.Xr chflags 1 ,
parses it, and returns the 'set' flags and 'clear' flags
such as would be given as arguments to
.Xr chflags 2 .
On success
.Fn setflags
returns 0, otherwise it returns non-zero and
.Fa stringp
is left pointing to the offending token.
