- * Purpose: Writes (part of) a DATASET to a file from application memory
- * BUF. See H5Dwrite() for complete details.
+ * Purpose: Writes multiple (part of) DATASETs to a file from application
+ * memory BUFs. See H5Dwrite_multi() for complete details.
*
- * Return: Non-negative on success/Negative on failure
+ * This was referred from H5D__write for multi-dset work.
*
- * Programmer: Robb Matzke
- * Thursday, December 4, 1997
+ * Return: Non-negative on success/Negative on failure

+ *
+ * The operations can use either hyperslab or point

+ * contiguous layout, use of multiple datasets and H5D*_multi
+ * calls, and use of the "shapesame" algorithm code path. To
+ * avoid the shapesame path when that option is not set, this
