Member Function Documentation

bool hadaq::HldFile::OpenRead ( const char * fname )

Opened file for reading.

Internal buffer required when data read partially and must be kept there.

bool hadaq::HldFile::ReadBuffer	(	void *	ptr,
		uint32_t *	bufsize,
		bool	onlyevent = `false`
	)

Read one or several elements to provided user buffer When called, bufsize should has available buffer size, after call contains actual size read.

If /param onlyevent=true, the only hadaq element will be read. Returns true if any data were successfully read.

bool hadaq::HldFile::WriteBuffer	(	void *	buf,
		uint32_t	bufsize
	)

Write user buffer to file without reformatting User must be aware about correct formatting of data.

Returns true if data was written.
