// Define version macros for the rocJPEG API dispatch table, specifying the MAJOR and STEP versions.
//
// !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!     IMPORTANT    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//
// 1. When adding new functions to the rocJPEG API dispatch table, always append the new function pointer
//    to the end of the table and increment the dispatch table's version number. Never rearrange the order of
//    the member variables in the dispatch table, as doing so will break the Application Binary Interface (ABI).
// 2. In critical situations where the type of an existing member variable in a dispatch table has been changed
//    or removed due to a data type modification, it is important to increment the major version number of the
//    rocJPEG API dispatch table. If the function pointer type can no longer be declared, do not remove it.
//    Instead, change the function pointer type to `void*` and ensure it is always initialized to `nullptr`.
//
// !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//

// The major version number should ideally remain unchanged. Increment the ROCJPEG_RUNTIME_API_TABLE_MAJOR_VERSION only
// for fundamental changes to the rocJPEGDispatchTable struct, such as altering the type or name of an existing member variable.
// Please DO NOT REMOVE it.
#define ROCJPEG_RUNTIME_API_TABLE_MAJOR_VERSION 0

// Increment the ROCJPEG_RUNTIME_API_TABLE_STEP_VERSION when new runtime API functions are added.
// If the corresponding ROCJPEG_RUNTIME_API_TABLE_MAJOR_VERSION increases reset the ROCJPEG_RUNTIME_API_TABLE_STEP_VERSION to zero.
#define ROCJPEG_RUNTIME_API_TABLE_STEP_VERSION 0
