simple… return integer to unicode character parameter.

 

It occurs all of the time, you track internal business function success or failure as an integer, and then you finally want to return it to NER / ER / TER as a char, but a double byte char because it’s unicode.

This is somewhat painful, but I have the remedy.  It also uses the crazy ?: operator, which is sure to confuse all of your friends.

In this case if i is non 0, it’ll return 1, else it’ll return 0 – nice.

       lpDS->cErrorCode=i?_J('1'):_J('0') ;

This could be written:

if (i != 0)

{

lpDS->cErrorCode=_J(‘1’) ;

}

else

{

lpDS->cErrorCode=_J(‘0’) ;

}
