buffer of elements by selected type. More...

## Functions
uint | epr_copy_field_elems_as_ints (const EPR_SField *field, int *buffer, uint num_elems)
uint | epr_copy_field_elems_as_uints (const EPR_SField *field, uint *buffer, uint num_elems)
uint | epr_copy_field_elems_as_floats (const EPR_SField *field, float *buffer, uint num_elems)
uint | epr_copy_field_elems_as_doubles (const EPR_SField *field, double *buffer, uint num_elems)

## Detailed Description

buffer of elements by selected type.

The actual number of elements copied is the minimum of the given number of elements (the buffer's size) and the actual number of elements contained in the field.

If the actual field data type is not selected type, the function automatically performs the conversion.

Parameters:

  | field | the field from which to copy the elements
  | buffer | the buffer in which to copy the data
  | num_elems | the number of elements in the given buffer

Returns:
  the actual number of elements copied
