Subject: does this code break the strict-aliasing rules ?
Date: Tue, 06 Feb 2007 15:58:00 -0000	[thread overview]
Message-ID: <1170777494.30181.38.camel@sapc154> (raw)

Hi,

encountering strange results, I'm unsure whether this code is affected
by strict-aliasing rules:

static void *CreateRes(PrexecTresource eRes, void *pvVal)
{
    switch(eRes) {
    case PrexecNprintCommand:
    case PrexecNoptHost:
    case PrexecNoptHostString:
    case PrexecNoptDest:
    case PrexecNoptDestString:
    case PrexecNoptFileString:
        if (pvVal != NULL) {
            pvVal = (void*)strdup((char*)pvVal);
        }
        break;
    default:
        break;
    }

    return pvVal;
}

Specifically the casts around the 'strdup'...

Thanks,
  /haubi/
