Simple PerlEz Sample

choeppner has asked for the wisdom of the Perl Monks concerning the following question:

I am looking for something just a little more than the manual pages.

I want to use PerlEzCreate, PerlEzCall, and PerlEzDelete to call a sub within from VC++.

I cannot find a simple sample anywhere. Anyone got one or have a link to one?

I have only seen code samples for perl_construct, call_argv, and perl_destruct and have not been able to apply this to the other method with success.

      Thanks, I will give it a look.
        For pennance to the Monastery, I hammered out the sample that I was searching for.

        // test.cpp : Defines the entry point for the console application. // /* --Contents of "" sub ezsub($) { my $param = shift; return qq(Parameter passed in is -$param-\n); } */ #include "stdafx.h" #include <windows.h> #include <perlez.h> int _tmain(int argc, _TCHAR* argv[]) { char cmd[80]; char buffer[200]; PERLEZHANDLE perl = PerlEzCreate("", NULL); if(!perl) return 1; int nInteger = 234; if(PerlEzCall(perl,"ezsub",buffer,sizeof(buffer),"i", nInteger)==0) printf("1 - %s\n", buffer); sprintf(cmd, "ezsub"); char *szString = "456"; if(PerlEzCall(perl,cmd,buffer,sizeof(buffer),"s",szString)==0) printf("2 - %s\n", buffer); sprintf(cmd,"ezsub('%s')",szString); if(PerlEzEvalString(perl,cmd,buffer,sizeof(buffer))==0) printf("3 - %s\n", buffer); PerlEzDelete(perl); return 0; }
        1 - Parameter passed in is -234- 2 - Parameter passed in is -456- 3 - Parameter passed in is -456-
        ...And please forgive me for posting C code in this sacred place of Perl.
