STRTOFFLAGS(3)						   BSD Library Functions Manual 					    STRTOFFLAGS(3)

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. BSD

STAT_FLAGS(3)						   BSD Library Functions Manual 					     STAT_FLAGS(3)

string_to_flags, flags_to_string -- Stat flags parsing and printing functions LIBRARY
System Utilities Library (libutil, -lutil) SYNOPSIS
#include <util.h> char * flags_to_string(u_long flags, const char *def); int string_to_flags(char **stringp, u_long *setp, u_long clrp); DESCRIPTION
The flags_to_string() and string_to_flags() functions are used by programs such as ls(1), mtree(8), makefs(8), etc., to parse and/or print the st_flags field in the stat(2) structure. They recognize the following flags: String Flag Description arch SF_ARCHIVED file is archived nodump UF_NODUMP do not dump file opaque UF_OPAQUE directory is opaque in union filesystems sappnd SF_APPEND writes to the file may only append schg SF_IMMUTABLE file cannot be changed; it is immutable snap SF_SNAPSHOT file is a snapshot inode uappnd UF_APPEND writes to the file may only append uchg UF_IMMUTABLE file cannot be changed; it is immutable The SF_APPEND and SF_IMMUTABLE flags are for the superuser only, whereas UF_APPEND and UF_IMMUTABLE are for the user only. The flags_to_string() function converts the bits set in the flags argument to a comma-separated string and returns it. If no flags are set, then the def string is returned. The returned string is allocated via malloc(3) and it is the responsibility of the caller to free(3) it. The string_to_flags() function takes a stringp of space, comma, or tab separated flag names and places their bit value on the setp argument. If the flag name is prefixed by: ``no'', then the bit value is placed on the clrp argument. RETURN VALUES
flags_to_string() returns the symbolic representation of flags, the default string, or NULL if allocation failed. string_to_flags() returns 0 on success and 1 if it fails to parse the string, setting stringp to point to the first string that it failed to parse. SEE ALSO
