The most reliable way to do it is to use Directory Services.
There is no official Obj-C DS API (The DSObjcWrapper is part of
darwin and is open sources but it's a private framework) and the C API
is fairly complex.
But, POSIX call uses Directory Service API under the hood, so using
the BSD API is probably the way to go:
#include <sys/types.h>
#include <pwd.h>
int main () {
struct passwd *p;
while ((p = getpwent())) {
// Note: p->pw_uid is declared as an unsigned int,
// but Darwin uses it as an signed value (nobody has id -2), so
you have to cast it
if ((int32_t)p->pw_uid >= 500) {
printf ("id %d = '%s'\n", p->pw_uid, p->pw_name);
} else {
printf ("(system) - id %d = '%s'\n", p->pw_uid, p->pw_name);
}
}
return 0;
}
