SL_SortListFunc


NAME
SL_SortListFunc -- sort a list with a user supplied compare function.

SYNOPSIS
SL_SortListFunc(list, function);
A0 A1

SL_SortListFunc(LISTHANDLE, WORD (*)(void *, void *));

FUNCTION
Sorts the supplied list using the supplied compare function to
determine sort order.

The function returns:
<0 if the first node is less than the second node
=0 if the first node is equal to the second node
>0 if the first node is greater than the second node

This return scheme is the same as the standard C function strcmp().

INPUTS

list - a LISTHANDLE as returned by SL_CreateListA.
func - a pointer to the compare function.

NOTE
The function argument must be declared using SL_CALLBACK.

EXAMPLE
SL_SortListFunc(list, &sortbyname);

SL_CALLBACK WORD sortbyname(void *n1, void *n2)
{
return(1'>2);
}
