_RetDateStr( ) API Library Routine Example

The following example converts a character string into a date data type and returns it to Visual FoxPro.

Visual FoxPro Code

SET LIBRARY TO RETDATES
? DATES("02/16/95")  && returns date {02/16/95}

C Code

#include <pro_ext.h>

void FAR dates(ParamBlk FAR *parm)
{
   MHANDLE mh;
   char FAR *instring;

   if ((mh = _AllocHand(parm->p[0].val.ev_length + 1)) == 0) 
   {
      _Error(182); // "Insufficient memory"
   }
   _HLock(parm->p[0].val.ev_handle);
   instring = _HandToPtr(parm->p[0].val.ev_handle);
   instring[parm->p[0].val.ev_length] = '\0';
   _RetDateStr(instring);
   _HUnLock(parm->p[0].val.ev_handle);
}

FoxInfo myFoxInfo[] = {
   {"DATES", (FPFI) dates, 1, "C"}
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
