Definitions are sorted by export status, category, package, and then by lexicographic order.
Returns the Adler-32 checksum of the given data, in the form s2 * 2^16 + s1.
Returns a fresh octet vector that contains the decompressed form of the
‘format’-compressed data in ‘input’.
‘output-size’, if not ‘nil’, should be the predicted size of the decompressed
data. If correct, this prevents unnecessary copying at the end.
If ‘allow-overreads-p’ is true and ‘input’ is a stream, bytes beyond the end of
the compressed data might end up being read during decompression; enabling this
option tends to significantly improve performance on stream inputs.
This function can take further format-specific options.
Returns the ‘format’ argument used to create ‘stream’.
Returns the header metadata of the data associated to ‘stream’.
Returns a list of symbols that can be used as ‘format’ arguments to ‘make-decompression-stream’ and ‘decompress’ to specify a compression format.
Returns a ‘decompression-stream’ whence the decompressed form of the
‘format’-compressed data in ‘input’ can be read. ‘input’ should not be modified
or read from until ‘decompression-stream’ has reached end of file. If ‘input’ is
a stream, then the caller is responsible for closing it.
Calling this function will read header information from ‘input’, but no decompression will be performed until data is read from ‘decompression-stream’.
If ‘allow-overreads-p’ is true and ‘input’ is a stream, bytes beyond the end of
the compressed data might end up being read during stream creation and
decompression; enabling this option tends to significantly improve performance
on stream inputs.
This function can take further format-specific options.
Returns a function suitable to be passed as a ‘dictionary’ argument for zlib decompression which recognizes every octet vector in the sequence ‘buffers’ and no others. The vectors should not be modified afterwards. An error is signalled if multiple vectors with distinct contents have the same checksum.
Returns the unrecognized checksum that was encountered during zlib decompression, in the form ‘adler-32’ outputs.

General superclass for errors related to decompression.
simple-error.
Signalled when the input stream/buffer is exhausted. Notably implies that the data up until this point was not detectably malformed. Note that even when the input is a stream, it is this condition which is signalled, not ‘end-of-file’.
Signalled when zlib decompression involves a preset dictionary whose checksum
isn’t recognized by the dictionary function.
Note: This condition is only signalled when preset dictionaries are enabled.

This slot is read-only.
Gray stream wrapper that can be used for complicated stream processing. The end of file is considered reached when the underlying compressed data ends and all associated uncompressed data has been read.

‘pushnew’ the format keyword to this once you’ve implemented a new format.
An ‘svref’ for constants that derives integer bounds if possible.
Returns whether the underlying byte source can be safely used. This can be guaranteed by consuming at least 22 bits without a call to ‘lbr-ensure-bits’.
Removes up to the next ‘n’ bits from the buffer in ‘br’.
Ensures that at least ‘n’ bits are buffered in ‘br’.
Discards buffered bits in ‘br’ before the next byte boundary. This function does NOT guarantee that bytewise I/O will be usable afterwards.
Returns and consumes the next ‘n’ bits in ‘br’.
Returns whether the underlying byte source can be safely used. This can be guaranteed by consuming at least 27 bits without a call to ‘mbr-ensure-bits’.
Removes up to the next ‘n’ bits from the buffer in ‘br’.
Ensures that at least ‘n’ bits are buffered in ‘br’.
Discards buffered bits in ‘br’ before the next byte boundary. This function does NOT guarantee that bytewise I/O will be usable afterwards.
Returns and consumes the next ‘n’ bits in ‘br’.
reps.
Reads the necessary data from the given ‘byte-source’ (see ‘io.lisp’) to create a decompression state for ‘format’. Returns two values: The decompression state that can be passed to ‘next-decompressed-chunk’ later and a plist of header metadata which will be returned to the user.
