Re: Data translation question

[Bruce Vining <bvining@xxxxxxxxxx>]

There is one consideration to using getpwnam() that may not be obvious.
The returned path is in the CCSID of the current job and there can be data
loss if elements of the path associated with the user profile contain
characters not in your current CCSID.  If you intend to work only with one
language environment on your system then this may be OK.

QSYRUSRI is not as straight forward for some users to use as it returns the
path in Unicode, but the use of Unicode is what also allows the application
to retrieve the path without worrying about what CCSID might be in use at
the current time.  For developers writing generic routines that may run
anywhere in the world the use of Unicode does actually simplify their
development effort.

You can use the iconv() API to translate the result. There should be
examples of calling the iconv() API in the archives, I'm pretty sure I've
posted some before.  If you can't find any, let me know.

Personally, I'd use the getpwnam() API to get the home directory. It's
just easier to use. Here's an example of an RPG program that's intended to
be called by CL to get a user's home directory:

      H DFTACTGRP(*NO)

      D passwd          DS                  qualified
      D                                     BASED(Template)
      D  pw_name                        *
      D  pw_uid                       10U 0
      D  pw_gid                       10U 0
      D  pw_dir                         *
      D  pw_shell                       *

      D getpwnam        PR              *   ExtProc('getpwnam')
      D   name                          *   Value options(*string)

      D p_info          s               *
      D info            ds                  likeds(passwd)
      D                                     based(p_info)

      D peUser          s             10A
      D peHomeDir       s            256A

      C     *entry        plist
      c                   parm                    peUser
      c                   parm                    peHomeDir

      c                   eval      p_info = getpwnam(%trimr(peUser))
      c                   if        p_info = *NULL
      c*** error occurred. Check errno to find out what went wrong.
      c                   endif

      c                   eval      peHomedir = %str(info.pw_dir)
      c                   return
