Difference between crash dump and hang dump?

Question

What is the difference between crash-dump and hang-dump?

Suppose if i write a utility to create a dump of a process on clicking it, how will i intimate the utility to create an appropriate dump?

Answer 1

Not sure what you mean, they are both dumps of the application/kernel state (memory) in varying levels of detail. Whether the application has hung or crashed is kind of irrelevant in terms of what constitutes a dump see this doc and here http://www.debuginfo.com/articles/easywindbg2.html#savedumps what crash dump will have are the exception records of the crash itself.
