Re: C program for QDFRTVFD API

Hi Jevgeni

Thank you for the correction. I have modified my code.
I should have known this but just shows I need more practice.
I believe I have learnt now there is nothing magic about C functions.
If the string variable is not null terminated you need to handle lengths
explicitly.
Seems that strcmp and sizeof need null terminated strings to work.
Also the original code mostly worked Ok, because the row and col are 1 byte
values and I
did not have more than one field in the same place.

Regards
Frank

This part of code is invalid, I think:
-snip
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;
