zlibVersion |
Supported. |
Returns '1.2.7-zEDC' |
deflateInit |
Supported. |
|
deflate |
All flush modes are supported. |
If the input buffer size is smaller than the
minimum threshold for zEDC on the first call to deflate (compress)
a data stream, the data stream is compressed using traditional software-based
compression. |
deflateEnd |
Supported. |
|
inflateInit |
Supported. |
|
inflate |
Supported if the flush mode is one of the following: - z_no_flush
- z_sync_flush
- z_finish
|
If either the input buffer size is smaller than
a minimum threshold for zEDC or the flush mode is z_block or z_trees
on the first call to inflate (decompress) a data stream, the data
stream is decompressed using traditional software-based decompression. On
subsequent calls to inflate a data stream, if the flush mode is z_block
or z_trees and the stream is using zEDC decompression, Z_STREAM_ERROR
is returned
|
inflateEnd |
Supported. |
|
deflateInit2 |
Support is based on the input parameters. |
Input parameters:- level
- This option is ignored for zEDC and does not affect the software
or zEDC compression decision.
This option is supported for zlib
software compression.
- method
- Must be Z_DEFLATED.
- windowBits
- Must be -15 for raw deflate, 15 for zlib header and trailer, or
31 for gzip header and trailer. For all other windowBits values, the
data stream uses traditional software-based compression.
- memLevel
- This option is ignored for zEDC and does not affect the software
or zEDC compression decision.
This option is supported for zlib
software compression.
- strategy
- Use Z_DEFAULT_STRATEGY or Z_FIXED for zEDC. All other options
use traditional software-based compression.
|
deflateSetDictionary |
Supported. |
This option is supported for zEDC when called
before the first deflate call for the data stream and is not supported
after the first call to deflate. |
deflateCopy |
Supported. |
|
deflateReset |
Supported. |
|
deflateParams |
Support is based on the input parameters. |
Input parameters:- Level
- This option is ignored for zEDC.
- Strategy
- Use Z_DEFAULT_STRATEGY or Z_FIXED for zEDC. All other options
use traditional software-based compression.
|
deflateTune |
Supported. |
This option only applies to traditional software-based
compression. zEDC accepts the call, but none of the parameters apply
to zEDC. |
deflateBound |
Supported. |
|
deflatePending |
Supported. |
|
deflatePrime |
Not supported for zEDC. |
Returns Z_STREAM_ERROR if the stream is using
zEDC. |
deflateSetHeader |
Supported. |
|
inflateInit2 |
Supported. |
|
inflateSetDictionary |
Supported if called immediately after a call
to inflate the data stream that returns Z_NEED_DICT. |
Otherwise, Z_STREAM_ERROR is returned if the
data stream is attempting to use zEDC decompression. |
InflateSync |
Supported. |
|
inflateCopy |
Supported. |
|
inflateReset |
Supported. |
|
inflatateReset2 |
Supported. |
|
inflatePrime |
Not supported for zEDC. |
Returns Z_STREAM_ERROR if the stream is using
zEDC decompression. |
inflateMark |
Not supported for zEDC. |
Returns Z_STREAM_ERROR if the stream is using
zEDC decompression. |
inflateGetHeader |
Supported. |
|
inflateBackInit |
Not supported for zEDC. |
InflateBackInit forces stream to software-based
compression. |
inflateBack |
Not supported for zEDC. |
|
zlibCompileFlags |
Supported. |
|
compress |
Supported. |
|
compress2 |
Supported. |
Level is ignored if using zEDC. |
compressBound |
Supported. |
|
uncompress |
Supported. |
|
gz* routines |
Not supported for zEDC. |
Uses software-based compression for inflate
and deflate functions. |
checksum functions |
Not supported for zEDC. |
Checksum functions calculate the checksum values
using software-based compression services. |
