/** @brief Make a copy of parts of an array.
|
|
*
|
|
* The source array may or may not be a record field.
|
|
*
|
|
* The increment parameter is used to support array filters; it
|
|
* means: copy only every increment'th element, starting at offset.
|
|
*
|
|
* The offset and no_elements parameters are used to support the
|
|
* circular buffer feature of record fields: elements before offset
|
|
* are treated as if they came right after no_elements.
|
|
*
|
|
* This function does not do any conversion on the array elements.
|
|
*
|
|
* Preconditions:
|
|
* nRequest >= 0, no_elements >= 0, increment > 0
|
|
* 0 <= offset < no_elements
|
|
* pto points to a buffer with at least field_size*nRequest bytes
|
|
* pfrom points to a buffer with exactly field_size*no_elements bytes
|
|
*
|
|
* @param pfrom Pointer to source array.
|
|
* @param pto Pointer to target array.
|
|
* @param field_size Size of an array element.
|
|
* @param nRequest Number of elements to copy.
|
|
* @param no_elements Number of elements in source array.
|
|
* @param offset Wrap-around point in source array.
|
|
* @param increment Copy only every increment'th element.
