netsnmp_create_handler_registration

Hi,

During a SET operation the custom handler will be called 4 times, 2 with old values and 2 with new ones (Reserve1, Reserve2, Action, Commit). If the same handler is used also for GET operations (HANDLER_CAN_RWRITE) will be called once only (let's call it Reserve1). How can one distinguish between GET and SET calls? Or even better can anyone tell apart the different stages alltogether from another within the custom handler?

This is mostly for efficiency reasons. I could read the table from the application in all stages before action, but if the table has a lot of data it creates a lot of unnecessary I/O and delays. An example:

dotable -> Reserve1? -> Is it get or set? If get I need I/O and remain on Reserve1. If set do nothing and advance to Reserve2. 
dotable-> Reserve2? -> Is it new get Reserve1 or old set Reserve2? If get need I/O and stay on Reserve1. If set do nothing and advance to Action.

Variables are identical in these cases and do not help in discriminating them.

TIA,
Nikos
