char *
flags_to_string(u_long flags, const char *def);
int
string_to_flags(char **stringp, u_long *setp, u_long clrp);
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.
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.
