Re: Unix API read()

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

It seems from the data that it is being padded *before* the
OD 25.  So each record would be a different length.

DB2 files all have records of the same length.  There are no
variable length records (don't take that as an absolute, as I'm
sure someone could come up with a SQL file that has variable
length records).

Try creating the record length on the read function to longer
than the records are.  That is, if you are expecting 176 length
records, actually ask the unix read function to read 255 length
records.  The end of the record should be padded with spaces (x40)
or maybe nulls (x00).

I think the error is probably coming from you specifying 176 length
records, and since the record is longer than 176 the call is complaining
that it didn't read the entire records, which it didn't.
