Module gzip

Functions that read and write gzipped files.

The user of the file doesn't have to worry about the compression, but random access is not allowed.

Classes

GzipFile
The GzipFile class simulates most of the methods of a file object with the exception of the readinto() and truncate() methods.

Functions

U32(i)
Return i as an unsigned integer, assuming it fits in 32 bits.

LOWU32(i)
Return the low-order 32 bits of an int, as a non-negative int.

write32(output, value)

write32u(output, value)

read32(input)

open(filename, mode='rb', compresslevel=9)
Shorthand for GzipFile(filename, mode, compresslevel).

_test()

Variables

FCOMMENT = 16

FEXTRA = 4

FHCRC = 2

FNAME = 8

FTEXT = 1

READ = 1

WRITE = 2

Imports: struct, sys, time, zlib, __builtin__

Function Details

Return i as an unsigned integer, assuming it fits in 32 bits.

If it's >= 2GB when viewed as a 32-bit unsigned int, return a long.

Shorthand for GzipFile(filename, mode, compresslevel).

The filename argument is required; mode defaults to 'rb' and compresslevel defaults to 9.
