<div class="textblock"><p>A simple refcounted data type representing an immutable byte sequence from an unspecified origin. </p>
<p>The purpose of the <a class="el" href="classGlib_1_1Bytes.html" title="A simple refcounted data type representing an immutable byte sequence from an unspecified origin...">Bytes</a> class is to keep the memory region that it holds alive for as long as anyone holds a reference to the bytes. When the last reference count is dropped, the memory is released. Multiple unrelated callers can use byte data in the <a class="el" href="classGlib_1_1Bytes.html" title="A simple refcounted data type representing an immutable byte sequence from an unspecified origin...">Bytes</a> object without coordinating their activities, resting assured that the byte data will not change or move while they hold a reference.</p>
<p>A <a class="el" href="classGlib_1_1Bytes.html" title="A simple refcounted data type representing an immutable byte sequence from an unspecified origin...">Bytes</a> object can come from many different origins that may have different procedures for freeing the memory region. Examples are memory from g_malloc(), from memory slices, from a GMappedFile or memory from other allocators.</p>
