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;

Hi Jevgeni

I am glad your program is now working, it was your original question
that prompted my to make a program that uses the API.

Seems there are many ways to skin a cat and what you say to store the
pointer of the previous field is more efficient.

You mention debugging my program.
What bug did you find? I would like to correct it.
As you may guess I dont believe my code is 'dangerously inefficient'.
Yes my code is not the most efficient but it was mostly a demonstration
of how to process the API data, and as such it has succeeded.
