multiple definitions error

[CINC]

I'm using the Metrowerks Codewarrior compiler, and I am trying to do something like this in a for loop, inside a void function:

if ((structArray.info & someMask) == someMask)
{
cout << &quot;something&quot; << endl;
}

all I did was define three different masks globally in a header file then:
in a function in my implementation file, I used the bitwise or-- | --to set the above variable, using the masks, and based on a simple boolean expression
in another function in that same file I did the above with the same three masks

thank you

you have a couple of options.

1 put
#ifndef MASKS_H
#define MASKS_H

int maskLLow = 0xFF;
int maskULow = 0xFF00;

etc

#endif


into your header file... if this does not work. In a cpp file declare the masks

in the header file, do not put in the ifdefs and instead put

extern int maskLLow;
extern int maskULow;

etc..


Then include that h file everywhere you need the mask values
