[CVI2015] Max size of a string

Hello, 

I have read in the CVI documentation that the string maximum size is 2^31. 

The problem is with realloc() function or with static normal declaration, the max size of a string I can have is 10 000 char. (from zero to 9999). 

Is it normal ? I need to allocate much more then that for my app. 

Any help please ? 

Regards,
