# Error Handling

Almost all of the APIs available from the EIL return `EILReturnCode`. The documentation for each function Error Handling outlines the potential return conditions. Every effort has been made to ensure that invalid usage of the IL is caught and presented with a meaningful return code. Additionally, a log error or warning will typically be issued via the logging mechanism.
