I did some research and it seems that what you need is not programmatically implemented, so you have to think about it a bit. Would a test to see whether the resumed guest is ready or not to accept commands suit your purposes?
I *think* that if via vmrun you e.g. ask the guest to check for the existence of a file, or provide a listing of a directory, when the guest is not ready, there will be some kind of error. On the other hand, if the guest is ready (i.e. fully resumed) the command will provide a result without error.
The example I have in mind is the following, taken from chapter "Using vmrun to Work with Guest Operating Systems Files and Directories" in http://nuclear.unh.edu/wiki/index.php?title=Using_VMWare_vmrun
To check for the existence of a particular file:
vmrun -T server -h https://hostname:8333/sdk -u root -p mypassword -gu fred -gp guestpasswd fileExistsInGuest "[Vol1] CentOS 5.2/CentOS 5.2.vmx" /home/fred/MyFile
The file exists.
The above is just a blind guess from my part, I am sure there are more elaborated ways to answer your question, depending the way you need to be informed about the status of the guest resume process. If you are working on local guests you just wait for it to resume in the GUI :), but if you are working with a remote guest there should be a way to do this in a clever and efficient way.
