One of the c + + struct typedef struct _tagEQDATA function object operator () (int, int), in comparison, return a pointer to a function

 
EQVARIENT * operator () (const unsigned int code, const unsigned int indicator, const unsigned int the date=0) 
{
EQVARIENT * pEQVar=NULL; 
If (valueArray. NSize==0) 
{
Return pEQVar; 
} 

If (valueArray nSize!=codeArray) nSize * dateArray) nSize * indicatorArray nSize) 
{
Return pEQVar; 
} 

If (code & lt; CodeArray. NSize & amp; & Indicator & lt; IndicatorArray. NSize & amp; & The date & lt; DateArray. NSize) 
{
Int nIndex=codeArray) nSize * indicatorArray) nSize * date + indicatorArray nSize * code + indicator; 
PEQVar=valueArray. PEQVarient; 
PEQVar +=nIndex; 
} 

Return pEQVar; 
}
