Re: AfxIsValidAddress equivalent, test valid memory



Oops, forgot to free the malloc'ed memory (never did
that before:-)
-brendan

Boolean
memIsValid(vm_address_t m_addr, size_t numOfBytes)
{
    vm_address_t dstPtr =
(vm_address_t)malloc(numOfBytes);
    mach_port_t thisTask = mach_task_self();
    vm_size_t sizeRead = numOfBytes;
    int err;

    err = vm_read_overwrite(thisTask, m_addr,
numOfBytes, dstPtr, &sizeRead);

    if (err == noErr && sizeRead != numOfBytes)
        err = -1;

    free ((void*)dstPtr);  // !!

    return (err == noErr);
}
