[Carbon] how do i get a list of users and groups??

[Logan Murray]

hey all, i've been struggling to figure out how to get a list of users and
groups like the finder's get info window displays in its ownership &
permissions section.

i'm not too familiar with unix, and i'm using carbon to write this program
(on os x) and haven't found anything in apple's documentation (big surprise)
except for the function PBGetUGEntrySync which i can't get to work for the
life of me (i keep getting -50 errors for every possible variation of the
parameters).

if anyone out there knows how to do this (seemingly normal) task, please
post back.

thanks in advance,
logan

In the "System" framework. Available to Mach-O programs, or, if you are
using CFM, you can use:

CFURLCreateCopyAppendingPathComponent()
CFBundleCreate()
CFBundleLoadExecutable()
CFBundleGetFunctionPointerForName()

to get a function pointer you can execute out of the System framework.
(I'll post a sample code fragment if you want.)

getpwent and getgrent are documented with man pages. In a "Terminal"
window, say:

man getpwent


You can search the man database using

apropos

# or

man -k

But, you might need to run the command-line command
