You are right, the declaration of the i variable in the for is not standard C programming... but I use cpp :-)

Here is the code without it:

Code:

#include <stdio.h>
#include <locale.h>
#include <wchar.h>

  int main()
  {
        wchar_t arab[4] = { 1583, 1575, 1605, 0 };
        wchar_t engl[4] = { 65, 66, 67, 0 };
        wchar_t temp[4] = { 0, 0, 0, 0 };
        int i = 0;

        printf("\n#1 copy arab into temp");
        wsprintf(temp, "%S", arab);
        printf("\narab bytes : "); for (i=0; i<4; i++) printf("%d ", (int) arab[i]);
        printf("\ntemp bytes : "); for (i=0; i<4; i++) printf("%d ", (int) temp[i]);
        printf("\n");

        printf("\n#2 copy engl into temp");
        wsprintf(temp, "%S", engl);
        printf("\nengl bytes : "); for (i=0; i<4; i++) printf("%d ", (int) engl[i]);
        printf("\ntemp bytes : "); for (i=0; i<4; i++) printf("%d ", (int) temp[i]);

        printf("\n\n");
        return 0;
  }

Regarding the wsprintf, it's a rather standard wchar function, located in /usr/include/wchar.h (by default) in AIX. Under SunOS, I think it's declared in /usr/include/widec.h.

						       TPM Management - tpm_changeownerauth

NAME

       tpm_changeownerauth - change the authorization data associated with the owner or SRK

SYNOPSIS

       tpm_changeownerauth [OPTION]

DESCRIPTION

       tpm_changeownerauth allows for changing the authorization data for the TPM owner or the TPM's Storage Root Key (via the TPM_ChangeAuthOwner
       API).  This operation prompts for current password, followed by the new password and a confirmation of the new password. The --owner option
       changes the TPM owner password and --srk option changes the TPM's SRK password. The --well-known option is used when SRK or owner passwords
       need to be changed and current owner password is a secret of zeros, --set-well-known option changes current password to a secret of zeros,
       both options do not work by themselves, they must be used with --owner and --srk options to indicate which of these passwords will be
       changed.

       -h, --help
	      Display command usage info.

       -v, --version
	      Display command version info.

       -l, --log [none|error|info|debug]
	      Set logging level.

       -u, --unicode
	      Use TSS UNICODE encoding for passwords to comply with applications using TSS popup boxes

       -o, --owner
	      Change the authorization data for the TPM owner.

       -s, --srk
	      Change the authorization data for the TPM's Storage Root Key.

       -g, --original_password_unicode
	      Use TSS UNICODE encoding for original password to comply with applications using TSS popup boxes

       -n, --new_password_unicode
	      Use TSS UNICODE encoding for new password to comply with applications using TSS popup boxes

       -z, --well-known
	      Change password to a new one when current owner password is a secret of all zeros (20 bytes of zeros). It must be specified which
	      password (owner, SRK or both) to change

       -r, --set-well-known
	      Change password to a secret of all zeros (20 bytes of zeros). It must be specified which password (owner, SRK or both) to change
