LIBRARY

SYNOPSIS

#include <unistd.h>
char * fflagstostr (u_long flags);
int strtofflags (char **stringp u_long *setp u_long *clrp);

DESCRIPTION

The 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.

If memory cannot be allocated for the return value, fflagstostr ();
returns NULL

The value returned from fflagstostr ();
is obtained from malloc ();
and should be returned to the system with free ();
when the program is done with it.

The strtofflags ();
function takes a string of file flags, as described in chflags(1), parses it, and returns the 'set' flags and 'clear' flags such as would be given as arguments to chflags(2). On success strtofflags ();
returns 0, otherwise it returns non-zero and Fa stringp is left pointing to the offending token.
