Does anyone know why in pwd.h inside the password struct both pw_uid
and pw_gid items are defined as int's? Shouldn't they be uid_t and gid_t?
Also on a similar note in the grp.h file inside the definition of struct
group, item gr_gid is defined as an int and not gid_t.
from grp.h:
struct group {
<hack>
int gr_gid; /* group id */
<hack>
};
from pwd.h:
struct passwd {
<hack>
int pw_uid; /* user uid */
int pw_gid; /* user gid */
<hack>
};
from sys/types.h:
typedef unsigned long gid_t; /* group id */
typedef unsigned long uid_t; /* user id */
I realize that INT_MAX = 2,147,483,647(from machine/limits.h) which is
only half of ULONG_MAX. Even so, shouldn't pwd.h and grp.h be changed?
My main concern is that I am writing library functions that add/delete
users and groups and need to be able to print them out correctly. Currently
chpass(and the other password utils) print it out like this:
from src/usr.bin/chpass/pw_copy.c:
struct passwd *pw;
<hack>
(void)fprintf(to, "%s:%s:%d:%d:%s:%ld:%ld:%s:%s:%s\n",
pw->pw_name, pw->pw_passwd, pw->pw_uid, pw->pw_gid,
pw->pw_class, pw->pw_change, pw->pw_expire, pw->pw_gecos,
pw->pw_dir, pw->pw_shell);
