What's the point of malloc(0)?

Question

I just saw this code:

artist = (char *) malloc(0);

...and I was wondering why would one do this?

Answer 1

Not sure, according to some random malloc source code I found, an input of 0 results in a return value of NULL. So it's a crazy way of setting the artist pointer to NULL.
