streambuf & csdbg::streambuf::header ( )

virtual

Append LDP headers to the buffer.

Returns

*this

Exceptions

std::bad_alloc
csdbg::exception

Note

The appended headers are for:

1. executable absolute path
2. process ID
3. thread ID
4. timestamp (in microseconds)

Each header is formatted as 'name: value\r\n'. All the numeric values are hexadecimal. In LDP, the header section is terminated with a double \r\n followed by the message body (trace data). This method just appends the four headers (not the extra \r\n delimiter) to allow for custom headers before the trace data (exception headers, custom OEM headers e.t.c)
