Function Documentation

static int DListStrDataCmp ( const char *  sData1, const char *  sData2  )

inlinestatic

Node data comparator callback.

Parameters

sData1	Node 1 string data.
sData2	Node 2 string data.

Returns

Returns <0, 0, or >0 if pData1 is less than, equal, or greater than pData2, respectively.
