To access to the different fields of the estVector_t, it is necessary to specify the tag that correspond to a specific information type. Table 7.1 describes this correspondence. Some tags represent a list of values, one has to use the diet_est_array_* functions to have access to them. In Table 7.1, the second column marks these multi-value tags.
The tag ALLINFOS is a special: his field is always empty, but it allows to fill the vector with all known tags by the particular collector.
