hi, good night, how are you?

I'm trying to bring the swap item system to my hercules emulator and then launch it here in the community, I was successful, I'm just having a problem that according to the rathena commit they use the namespace std::map and std::pair that are C ++ languages not supported by hercules, how can I do this via struct or some function in C ?? Follow the link, if you can help I am grateful.

// No item equipped at the target

if( equippedItem == -1 ) {

// Remove it from the equip switch

pc_equipswitch_remove( sd, index );

pc_equipitem( sd, index, position );
