Mocking and Unit Test Coverage library in C

Which is a good library for mocking in C, similar to Mockito in Java ? I tried cmock, but was not successful and found documentation hard to understand.

Also suggest a unit test coverage framework for C, which can be integrated to Eclipse where I can see the covered and uncovered statements.

Someone suggested SWIG, where you convert C code to python and do the mocking using libraries in python. Will this be better than native C mocking ?
