It looks like the name for the c function: [gst_pipeline_get_state](https://github.com/RidgeRun/gstd-1.x/blob/master/libgstc/c/libgstc.c#L532) is different from all the other functions in that same header.. all the other ones start with **gstc_** There may be a good reason for this, but I thought i'd point it out.
