|
puff.c is a simple inflate written to be an unambiguous way to specify the
|
|
deflate format. It is not written for speed but rather simplicity. As a
|
|
side benefit, this code might actually be useful when small code is more
|
|
important than speed, such as bootstrap applications. For typical deflate
|
|
data, zlib's inflate() is about four times as fast as puff(). zlib's
|
|
inflate compiles to around 20K on my machine, whereas puff.c compiles to
|
|
around 4K on my machine (a PowerPC using GNU cc). If the faster decode()
|
|
function here is used, then puff() is only twice as slow as zlib's
|
|
inflate().
|
|
|
|
All dynamically allocated memory comes from the stack. The stack required
|
|
is less than 2K bytes. This code is compatible with 16-bit int's and
|
|
assumes that long's are at least 32 bits. puff.c uses the short data type,
|
|
assumed to be 16 bits, for arrays in order to to conserve memory. The code
|
|
works whether integers are stored big endian or little endian.
|
|
|
|
In the comments below are "Format notes" that describe the inflate process
|
|
and document some of the less obvious aspects of the format. This source
|
|
code is meant to supplement RFC 1951, which formally describes the deflate
|
|
format:
