Re: C program for QDFRTVFD API

This part of code is invalid, I think:

    if (!memcmp(Functn , "#NEXT"  , 5))
    {
      if (!memcmp(p_iRecord, Odata->RecordName, sizeof(*p_iRecord)))
      {
        if(!memcmp(p_iField, Odata->FldNam, sizeof(*p_iField) ))
        {
          if(!memcmp(p_iRow, Odata->ROW, sizeof(*p_iRow) ))
          {
            if(!memcmp(p_iCol, Odata->COL, sizeof(*p_iCol)))
            {
              *GotIt = 1;
            }
          }
        }
      }
    }

If understand correctly your intention, you wanted to compare 2 record
names, 2 field names, row and column of the 2 fields.
But in fact I think that you only compare the first character of the 2
records and the first character of the field names as
sizeof(*p_iRecord) equals to 1.

I would write it so:

   if (!memcmp(Functn , "#NEXT"  , 5)  &&
       !memcmp(p_iRecord, Odata->RecordName, 10) &&
       !memcmp(p_iField, Odata->FldNam, 10 ) &&
       (*p_iRow == *Odata->ROW) &&
       (*p_iCol == *Odata->COL))
              *GotIt = 1;
