ElementCountThe number of elements (not bytes) to read.
ptrA pointer to the first output element in an array (or std::vector<>, etc...).
Returns
The amound of bytes (not elements) actually read (under error situations, the last element may be invalid if the data stream abruptly ends). Example of usage:

Reads an object from stream, where its class must be the same as the supplied object, where the loaded object will be stored in.

Exceptions
std::exceptionOn I/O error or different class found.
mrpt::utils::CExceptionEOFOn an End-Of-File condition found at a correct place: an EOF that abruptly finishes in the middle of one object raises a plain std::exception instead.

◆ Seek() [1/2]

virtual uint64_t mrpt::utils::CStream::Seek ( int64_t  Offset,
CStream::TSeekOrigin  Origin = sFromBeginning 
)
pure virtualinherited

Introduces a pure virtual method for moving to a specified position in the streamed resource.

he Origin parameter indicates how to interpret the Offset parameter. Origin should be one of the following values:

  • sFromBeginning (Default) Offset is from the beginning of the resource. Seek moves to the position Offset. Offset must be >= 0.
  • sFromCurrent Offset is from the current position in the resource. Seek moves to Position + Offset.
  • sFromEnd Offset is from the end of the resource. Offset must be <= 0 to indicate a number of bytes before the end of the file.
    Returns
    Seek returns the new value of the Position property.

Implemented in mrpt::utils::CClientTCPSocket, mrpt::utils::CFileStream, mrpt::utils::CFileOutputStream, mrpt::utils::CFileGZInputStream, mrpt::utils::CMemoryStream, mrpt::utils::CFileInputStream, and mrpt::utils::CStdOutStream.

<HEADER> = A header byte
<LENGHT> = Number of bytes of BODY
<BODY> = N x bytes
<END_FLAG> = 0X96
Total length = <LENGTH> + 4

For frames of size > 255 the frame format is an array of bytes in this order:

<START_FLAG> <HEADER> <HIBYTE(LENGTH)> <LOBYTE(LENGTH)> <BODY> <END_FLAG>
<START_FLAG> = 0x79
