Look in the OutPutBin example, in the Initialize functionis you can find the
exact code to check if a PPD keyword is in the PPD file of the current Job.

A snippet from my code:

err = ppdOpenCompiledPPDFromTicket(printerInfo, &ppdContext,
&tempFSSpec);

if(err == noErr)
{
mIndex = ppdGetMainIndex(ppdContext, (const
StringPtr)kOCStaplePDEKey);

// no valid key found
if(mIndex == kPPDInvalidIndex)
{
err = kPMInvalidKey;
}
// close the PPD and delete the file
ppdCloseCompiledPPDFromTicket(ppdContext, &tempFSSpec);
}


KOCStaplePDEKey is defined as:
// PPD keys to look for in OCStaplePDE
const unsigned char* kOCStaplePDEKey = "\pOCStaplePDE";

The "*" is not included.

In my PPD the key is defined as:
*OCStaplePDE : True

Hope this is enough help for you.
