.Sh SYNOPSIS
|
|
.In unistd.h
|
|
.Ft char *
|
|
.Fn fflagstostr "u_long flags"
|
|
.Ft int
|
|
.Fn strtofflags "char **stringp" "u_long *setp" "u_long *clrp"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn fflagstostr
|
|
function returns a comma separated string of the file flags represented by
|
|
.Fa flags .
|
|
If no flags are set a zero length string is returned.
|
|
.Pp
|
|
If memory cannot be allocated for the return value,
|
|
.Fn fflagstostr
|
|
returns
|
|
.Dv NULL .
|
|
.Pp
|
|
The value returned from
|
|
.Fn fflagstostr
|
|
is obtained from
|
|
.Fn malloc
|
|
and should be returned to the system with
|
|
.Fn free
|
|
when the program is done with it.
|
|
.Pp
|
|
The
|
|
.Fn strtofflags
|
|
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 strtofflags
|
|
returns 0, otherwise it returns non-zero and
|
|
.Fa stringp
|
|
is left pointing to the offending token.
|
|
.Sh ERRORS
|
|
The
|
|
.Fn fflagstostr
|
|
function
|
|
may fail and set errno for any of the errors specified for the library
|
|
routine
|
|
.Xr malloc 3 .
