eee789b7ea continued: changed to overlapLog 
in deeper code layer.
for consistency.

9b784dec7f changed parameter name to ZSTD_c_overlapLog 
from overlapSizeLog.

Reasoning :
`overlapLog` is already used everwhere, in the code, command line and documentation.
`ZSTD_c_overlapSizeLog` feels unnecessarily different.

6ced8f7c7c joined normal streaming API with advanced one 2018-12-03 14:22:38 -08:00
Yann Collet
d8e215cbee created ZSTD_compress2() and ZSTD_compressStream2() 
ZSTD_compress_generic() is renamed ZSTD_compressStream2().

Note that, for the time being,
the "stable" API and advanced one use different parameter planes :
setting parameters using the advanced API does not influence ZSTD_compressStream()
and using ZSTD_initCStream() does not influence parameters for ZSTD_compressStream2().

d4d4e109e9 getParameter fills an int* 
rather than an unsigned*
for consistency
since type of setParameter() changed to int.

7b0391e37e finalized retrofit of ZSTD_CCtx_reset() 
updated all depending sources
 2018-11-14 13:05:35 -08:00
Yann Collet
ff8d371708 modified ZSTD_CCtx_reset() 
which now accepts an enum,
to distinguish between resetting the session, or the parameters (or both).

removed ZSTD_CCtx_resetParameters(), which is redundant.

start replacing invocation of ZSTD_CCtx_reset*() functions

Updated advanced API documentation

trimmed down amount of API staged in RC,
in particular, all functions related to ZSTD_CCtxParams()
seem too advanced.

d7e10a774a added constant ZSTD_WINDOWLOG_LIMIT_DEFAULT 
answering #1407.

Also : removed obsolete function ZSTD_setDStreamParameter()
which could only be used with one parameter (DStream_p_maxWindowSize).
Now replaced by ZSTD_DCtx_setWindowSize() (which exists since a few revisions)

b83d1e7714 removed some static const variables 
and replaced by traditional macro constants.

Unfortunately, C doesn't consider `static const` to mean "constant"
