Detailed Description

This group of functions is for getting the elements of a field as a typed value.

Typed value means that the returned variable is of a certain variable type, e.g. such as short or float.
The type is located in the field info. See epr_get_field_type.
One field must have one type only.

Parameters

field	the field, must not be NULL
elem_index	the zero-based index of element to be returned, must not be negative.

Returns

the typed value from given field
