bool dballe::AofFile::read |
( |
Rawmsg & |
msg | ) |
|
|
virtual |
Read a message from the file.
- Parameters
-
msg | The Rawmsg that will hold the data. |
- Returns
- true if a message has been found in the file, else false.
Implements dballe::File.

protected |
Read a Fortran Unformatted Sequential Binary record from a file.
- Parameters
-
res | The data read. The resulting data is an array of 32bit words that will be byteswapped to native endianness if needed. |
- Returns
