void* EPR_Field::elems

The elements of this field.

In order to use the data, this member must be casted to one of the following array data types:

1. unsigned char* - array of unsigned 8-bit integer elements
2. char* - array of signed 8-bit integer fields
3. unsigned short* - array of unsigned 16-bit integer elements
4. short* - array of signed 16-bit integer elements
5. unsigned int* - array of unsigned 32-bit integer elements
6. int* - array of signed 32-bit integer elements
7. float* - array of signed 32-bit floating point elements
8. double* - array of signed 64-bit floating point elements
9. EPR_STime* - array of MJD elements

Dedicated access routine are available The element type is given by info->data_type_id and the array length by info->num_elems.
