* 'dst' buffer must be already allocated.
* If dstCapacity >= LZ4_compressBound(srcSize), compression is guaranteed to succeed, and runs faster.
*
- * Important : The previous 64KB of compressed data is assumed to remain present and unmodified in memory!
+ * Important : The previous 64KB of source data is assumed to remain present and unmodified in memory!
*
* Special 1 : When input is a double-buffer, they can have any size, including < 64 KB.
* Make sure that buffers are separated by at least one byte.
