Redis RedisModule_SubscribeToKeyspaceEvent is thowing segmentation fault error while loading .so file into redis

By using keypace notification Modules API to I am using C++ to develop a module that registers for keyspace notifications, processes them.

I have Created RedisModule_OnLoad function, RedisModule_SubscribeToKeyspaceEvent And RedisModule_Init function, build it into .so file While loading the .so file in the redis server, it crashes and throws the segmentation fault ??

In what scenario the segmentation fault error occurs??

Actually the issue is resolved , In redismodule.h,

this needs to be added as I was creating a custom module

REDISMODULE_API int (RedisModule_SubscribeToKeyspaceEvents)(RedisModuleCtx ctx, int types, RedisModuleNotificationFunc cb) REDISMODULE_ATTR;
