# 6 Handler Functions

This chapter describes the handler functions available in SwitchKit. It provides prototype information, possible error return values, and a description of what the function does.

Most functions return an integer value. Upon successful completion, that return value is OK (0). Non-zero return values indicate some error conditions. Each function lists the associated error conditions.

Some functions return pointers; those functions do not have a status value indicating success or failure.
