that is: 128K for windowBits=15 + 128K for memLevel = 8 (default values)

plus a few kilobytes for small objects. For example, if you want to reduce

the default memory requirements from 256K to 128K, compile with

make CFLAGS="-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7"

Of course this will generally degrade compression (there's no free lunch).

The memory requirements for inflate are (in bytes) 1 << windowBits

that is, 32K for windowBits=15 (default value) plus a few kilobytes

for small objects.
