An Ethics Question

[Jeff Ferguson]

	Here's a pretty basic ethics question: how do the mighty C
programmers in netland have to say about global variables?  Take,
for example, the following two pieces of (idiotically simple) code:

/********* Example 1 **********/

FILE *fp;

main()
{
	/* code */
}

readfile()
{
	/* code */
}

/******** End Of Example 1 *********/

/******** Example 2 **********/

main()
{
	FILE *fp;

	/* code */
}

readfile(fp)
{
	/* code */
}

/******* End Of Example 2 ********/

Global variables or passed parameters?  I'm anxiously awaiting the pros
and cons of this issue.  Thank you.
