Error Handling

[Peter da Silva]

	"Do you want to try door #1, door #2, or door #3?"

	"Yes."

Door #1 (if(error) {cleanup; return;})

	If cleanup is relatively small.

Door #2 (if(!error) {next_step;})

	If there are relatively few cases, or you have religious reasons not
	to use #3 (i.e., it's on an exam)

Door #3 (if(error) goto cleanup;)

	If there are lots of cases and cleanup is nasty.

I've used all three.
