VisualWorks and Ghostscript.dll

VisualWorks and Ghostscript.dll

(OP)
I try using Ghostscript from a Smalltalk programm.

First I import Ghostscript.dll with "DLL & C Connect".
argv is selected as Array[10] of char*.

Thats the program:

gs:= GhostScript new.
inst:= gs gs_main_instance gcMalloc .
argv:= gs argv gcMalloc.

argv at:0 put: 'ps2pdf'.
argv at:1 put: '-dNOPAUSE'.
argv at:2 put: '-dBATCH'.
argv at:3 put: '-dSAFER'.
argv at:4 put: '-sDEVICE=pdfwrite'.
argv at:5 put: '-sOutputFile=out.pdf'.
argv at:6 put: '-c'.
argv at:7 put: '.setpdfwrite'.
argv at:8 put: '-f'.
argv at:9 put: 'c:\forget.ps'.

code:= gs gsapi_new_instance: inst with: nil.

"This return 0, that is no error."

"Then I do:"
code := gs gsapi_init_with_args: inst with: 10 with: argv.

"this returns error -25.

What is my error?

The end of that programm is..."

gs gsapi_exit: inst.
gs gsapi_delete_instance: inst.


Thanks
Wolfram
