This may be a simple lack of experience problem, but I can't see how my
data is being corrupted.  Here's the situation:

void SaveSprite(pSprite TheSprite,int *FileName)
	FILE *fp;

This alone changes some of the values in an array pointed to by a element
of the TheSprite structure.  The structure is defined as:

typedef struct Sprite
	int Height,Width;
	unsigned int *Bitmap;
} Sprite, *pSprite;

After the call to SaveSprite, the data in Bitmap is corrupted.  I malloced
and everything, and checked the data just before and just after the call,
and several bytes are changed.  Any assistance you could offer would be
greatly appreciated.
