<h5 id="C1_Zip_ZLib_ZStream_inflate_System_Int32__remarks">Remarks</h5>
<div class="markdown level1 remarks"><p><b>inflate</b> performs one or both of the following actions:</p>
<p>1. Decompress more input starting at <b>next_in</b> and update <b>next_in</b>
and <b>avail_in</b> accordingly. If not all input can be processed (because there 
is not enough room in the output buffer), <b>next_in</b> is updated and processing 
will resume at this point for the next call to inflate.</p>
<p>2. Provide more output starting at <b>next_out</b> and update <b>next_out</b>
and <b>avail_out</b> accordingly. <b>inflate</b> provides as much output as 
possible, until there is no more input data or no more space in the output buffer.</p>
<p>Before the call to inflate, the application should ensure that at least one of the 
actions is possible, by providing more input and/or consuming more output, and 
updating the <b>next_*</b> and <b>avail_*</b> values accordingly.</p>
<p>If <b>inflate</b> returns Zero and <b>avail_out</b> == 0, it must be called again 
after making room in the output buffer because there might be more output pending.</p>
<p>The application can consume the uncompressed output when it wants, for example when 
the output buffer is full (<b>avail_out</b> == 0), or after each call of <b>inflate</b>.</p>
<p>This method may introduce some output latency (reading input without producing 
any output) except when forced to flush.</p>
