* Programmer: Robb Matzke
* Monday, January 4, 1999

- * Modifications:
- * Robb Matzke, 1999-06-16
- * Added support for non-zero strides. If BUF_STRIDE is non-zero
- * then convert one value at each memory location advancing
- * BUF_STRIDE bytes each time; otherwise assume both source and
- * destination values are packed.
- *
- * Raymond Lu, 2011-05-26
- * When overflow happened, the old way was to fill in the destination
- * with 0xff. The new default way is to convert the source value
- * to the destination. If the user sets the property through
- * H5Pset_enum_conv_overflow, the library still uses the old way.
