STRTOFFLAGS(3)						   BSD 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(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 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.
