Problem:

Using byte stream file handling and cbl_read_file is not returning any data.

Return-code = 0 on  the cbl_open_file and receives Return_Code = 0 on the cbl_read_file

but no data is received into his input buffer-

Resolution:

One of the parameters for the cbl_read_file is flags.

This parameter can take the following values:

          0 Standard read

      128 Return the current file size in file-offset

Need to make sure after the initial read to obtain the size of the file that the flags is set to 0 to do a standard read. Setting the flags to 0 resolved the no data returned in the input buffer issue.
