STRTOFFLAGS(3)        DragonFly Library Functions Manual        STRTOFFLAGS(3)

NAME
     fflagstostr, strtofflags - convert between file flag bits and their
     string names

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     char *
     fflagstostr(unsigned long flags);

     int
     strtofflags(char **stringp, unsigned long *setp, unsigned long *clrp);

DESCRIPTION
     The fflagstostr() function returns a comma separated string of the file
     flags represented by 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 stringp is left pointing to
     the offending token.

ERRORS
     The fflagstostr() function may fail and set errno for any of the errors
     specified for the library routine malloc(3).

SEE ALSO
     chflags(1), chflags(2), malloc(3)

HISTORY
     The fflagstostr() and strtofflags() functions first appeared in
     FreeBSD 4.0.
