Typedef Documentation

IliCompareFunction

This type defines the prototype of a function that is called to compare two rows of a table.

The sorting order is defined by the columns parameter, which designates an array of colCount column positions. Each given column is sorted in the ascending or descending order of the values. The global functions IliAscOrder and IliDescOrder are used to indicate the type of sort. Example:

// Sorts in the ascending order of column 2
// Sorts in the descending order of column 3
static const IlInt columns[] = { IliAscOrder (2), IliDescOrder (3)  };
tbl->sortRows(columns, 2);

Parameters

buf1	The buffer of the first row.
buf2	The buffer of the second row.
colums	The column list to sort.
colCount	The column count.
userData	The user data. params parameter.
params	The parameters transmitted to the global callback. This array contains paramsCount character strings.

Returns

• +1 if the first row is greater than the second row.
• 0 if the rows are equal.
• -1 if the second row is greater than the first row.
