Those MatOps_Values are a perpetual maintenance hassle. I would replace them all with a boring list of assignment statements for any implemented functions, as in MatCreate_Nest. Then we wouldn't need any "dummy" entries, the order wouldn't matter, etc. If Microsoft would implement C99, we could use designated initializers: static struct _MatOps MatOps_Values = { .setvalues = MatSetValues_SeqAIJ, .mult = MatMult_SeqAIJ, ..... };
