? xctot("2/16/95 12:07am")

C Code

#include <pro_ext.h>

void FAR datetime(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';
   _RetDateTimeStr(instring);
   _HUnLock(parm->p[0].val.ev_handle);
}
FoxInfo myFoxInfo[] = {
   {"XCTOT", (FPFI) datetime, 1, "C"}
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
