522.0. "Lattice / Manx differences." by PLDVAX::SMCAFEE (Steve McAfee) Mon Jun 01 1987 18:32

    
    Could someone who is familiar with the two C compilers (LATTICE/MANX)
    post a summary of the syntatic and functional differences between
    the two.  Basically, I have Lattice and if I ever post any code
    I would like to at least try to remove any major nits which MANX
    would barf on.  I hope I not asking for much, I assume there are
    less than a dozen or so things to consider.  For example, there
    may be instances where Lattice assumes LONG declarations and MANX
    requires casting to LONG.  
    
    thanks,

	A major difficulty is indeed the 32 bit int vs. the 16 bit int. Specifically, anywhere in your code that you need more than 16 bits, then explicitly specify long. So if you are calling a library routine which expects a 32 bit int, and you are passing a constant, then cast the constant to a long by appending an L to it. Also, Manx is missing function prototypes, so don't included them in your code, or at least put a #define around them. James
