Detailed Description

Dataitem used to read the dataitem of type itemtype_e::TRACEHEAD.

This struct is used as a one member in union dataitem_t.

Member Function Documentation

uint32_t pottu::dataitem_tracehead_t::getChannelIdent_flag ( ) const

inline

Flag in the field chi.

Typically 1 means that the data is dc-level, not actual data.

void pottu::dataitem_tracehead_t::toCStringFull	(	char *	s,
		uint32_t	len
	)		const

inline

Get the content as a c string.

This is useful for debugging.

uint32_t pottu::dataitem_tracehead_t::samplelength

Number of samples following.

These samples are delivered right after this dataitem as dataitem_tracedata_t.
