[Cffi-devel] Is there anything in CFFI where I can cast an integer to a char and the result is a letter..

This is the code I'm referring to :         char c = (char)waitKey();         if( c == 27 )             break;         if( c == 'r' )         {..... The function waitKey, above, outputs an integer as return and it's being cast to a char to make the result a letter. Can this be done in CFFI.I have a CFFI wrapper for waitKey btw, that has an :int return
