Hi,

I'm implementing a simple Graph library for my uni project and since this is the first time I'm dealing with graphs, I would like to know which functions you guys consider to be most common and useful for Graph implementations...

So far, I have this:

graphInitialize()
graphInsertVertex()
graphRemoveVertex()
graphGetVertex()
graphGetVertexValue() (not implemented yet, not sure if I'll need it)
graphInsertEdge()
graphRemoveEdge()
graphLinkVertices() (this calls graphInsertEdge twice for bidirectional graph)
graphUnlinkVertices() (this calls graphRemoveEdge twice for bidirectional graph)
graphDestroy()

I know I'm missing a function do determine the shortest path, but I'm leaving that for last...

Do you think I'm missing any common/useful function?

helper functions as static functions or procedural functions?

i wonder if one should create a helper function in a class as a static function or just have it declared as a procedural function? i tend to think that a static helper function is the right way to go cause then i can see what kind of helper function it is eg.
