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(2);
}
