static int shop_sort ( const void *  a1, const void *  a2  )

static

Sort routine for shopinv. There are a lot of extra casts in here just to suppress warnings - it makes it look uglier than it really it. The format of the strings we get is type:name. So we first want to sort by type (numerical) - if the same type, then sort by name.

Parameters

a1
a2	items to compare.

Returns

-1 is a1 is less than a2, 1 if the opposite, 0 if equals.
