Calling C functions from C++ functions

[Deepak Siddananja]

Hi All,

I have an application which is a blend of C and C++ code. It was written initially for HP 10.20. Now, teh same application after building on 11i does not seem to work.

I have followed the approach given in teh link below:
http://www-306.ibm.com/software/data/informix/pubs/library/notes/machnote/sdk240uc1_hp.html

Some of the C functions are callable from the application. But the exact problem is when a C function tries to assign a value to a bool variable (passed from C++ function). In the C code, bool is #defined as int.

Can anybody help me out please.

Thanks
Deepak

I believe a bool is one byte in size, try type casting it to a char....see more info:
