* 1) All file i/o is done externally to these routines
|
|
* 2) Routines are symmetrical so inflate can feed into deflate
|
|
* 3) Routines can be easily integrated into wide range of applications
|
|
* 4) Routines are very portable, and use only ANSI C
|
|
* 5) No #defines in inflate.h to conflict with external #defines
|
|
* 6) No external routines need be called by these routines
|
|
* 7) Buffers are owned by the calling routine
|
|
* 8) No static non-constant variables are allowed

|
|
* this behaviour may change in the future. Before InflatePutBuffer
