Data Sections

All data parsed from a waveform file is organized in sections. Each file generates at least one section but it can generate several ones. This occurs for example if a file holds data from several simulator runs or several different analysis types.

As sections can be removed by closing a file, the index of a particular section and the number of sections can change. Therefore sections are not identified by their indexes but by a unique identifier. Before accessing a section's data, this unique section identifier must be retrieved by calling af_wp_get_section_identifier() in C or the equivalent functions for other interfaces.
