<h2>Description</h2>
<p>
<code class="function">glMapBufferRange</code> and
<code class="function">glMapNamedBufferRange</code> map all or part of
the data store of a specified buffer object into the client's
address space. <em class="parameter"><code>offset</code></em> and
<em class="parameter"><code>length</code></em> indicate the range of data in the
buffer object that is to be mapped, in terms of basic machine
units. <em class="parameter"><code>access</code></em> is a bitfield containing
flags which describe the requested mapping. These flags are
described below.
</p>
<p>
A pointer to the beginning of the mapped range is returned once
all pending operations on the buffer object have completed, and
may be used to modify and/or query the corresponding range of
the data store according to the following flag bits set in
<em class="parameter"><code>access</code></em>:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="constant">GL_MAP_READ_BIT</code> indicates that
the returned pointer may be used to read buffer
object data. No GL error is generated if the pointer
is used to query a mapping which excludes this flag,
but the result is undefined and system errors
(possibly including program termination) may occur.
</p>
</li>
<li class="listitem">
<p>
<code class="constant">GL_MAP_WRITE_BIT</code> indicates that
the returned pointer may be used to modify buffer
object data. No GL error is generated if the pointer
is used to modify a mapping which excludes this
flag, but the result is undefined and system errors
(possibly including program termination) may occur.
</p>
</li>
<li class="listitem">
<p>
<code class="constant">GL_MAP_PERSISTENT_BIT</code> indicates
that the mapping is to be made in a persistent
fassion and that the client intends to hold and use
the returned pointer during subsequent GL operation.
It is not an error to call drawing commands (render)
while buffers are mapped using this flag. It is an
error to specify this flag if the buffer's data
store was not allocated through a call to the
<a class="citerefentry" href="glBufferStorage.xhtml"><span class="citerefentry"><span class="refentrytitle">glBufferStorage</span></span></a>
command in which the
<code class="constant">GL_MAP_PERSISTENT_BIT</code> was also
set.
</p>
</li>
<li class="listitem">
<p>
<code class="constant">GL_MAP_COHERENT_BIT</code> indicates
that a persistent mapping is also to be coherent.
Coherent maps guarantee that the effect of writes to
a buffer's data store by either the client or server
will eventually become visible to the other without
further intervention from the application. In the
absence of this bit, persistent mappings are not
coherent and modified ranges of the buffer store
must be explicitly communicated to the GL, either by
unmapping the buffer, or through a call to
<a class="citerefentry" href="glFlushMappedBufferRange.xhtml"><span class="citerefentry"><span class="refentrytitle">glFlushMappedBufferRange</span></span></a>
or
<a class="citerefentry" href="glMemoryBarrier.xhtml"><span class="citerefentry"><span class="refentrytitle">glMemoryBarrier</span></span></a>.

The following <span class="emphasis"><em>optional</em></span> flag bits in

<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="constant">GL_MAP_INVALIDATE_RANGE_BIT</code>
indicates that the previous contents of the
specified range may be discarded. Data within this
range are undefined with the exception of
subsequently written data. No GL error is generated
if subsequent GL operations access unwritten data,
but the result is undefined and system errors
(possibly including program termination) may occur.
This flag may not be used in combination with
<code class="constant">GL_MAP_READ_BIT</code>.
</p>
</li>
<li class="listitem">
<p>
<code class="constant">GL_MAP_INVALIDATE_BUFFER_BIT</code>

buffer may be discarded. Data within the entire
buffer are undefined with the exception of
subsequently written data. No GL error is generated
if subsequent GL operations access unwritten data,
but the result is undefined and system errors
(possibly including program termination) may occur.
This flag may not be used in combination with
<code class="constant">GL_MAP_READ_BIT</code>.
</p>
</li>
<li class="listitem">
<p>
<code class="constant">GL_MAP_FLUSH_EXPLICIT_BIT</code>
indicates that one or more discrete subranges of the
mapping may be modified. When this flag is set,
modifications to each subrange must be explicitly
flushed by calling
<a class="citerefentry" href="glFlushMappedBufferRange.xhtml"><span class="citerefentry"><span class="refentrytitle">glFlushMappedBufferRange</span></span></a>.
No GL error is set if a subrange of the mapping is
modified and not flushed, but data within the
corresponding subrange of the buffer are undefined.
This flag may only be used in conjunction with
<code class="constant">GL_MAP_WRITE_BIT</code>. When this
option is selected, flushing is strictly limited to
regions that are explicitly indicated with calls to

<code class="constant">GL_MAP_UNSYNCHRONIZED_BIT</code>
indicates that the GL should not attempt to
synchronize pending operations on the buffer prior
to returning from
<code class="function">glMapBufferRange</code> or
<code class="function">glMapNamedBufferRange</code>. No GL
error is generated if pending operations which
source or modify the buffer overlap the mapped
region, but the result of such previous and any
subsequent operations is undefined.

</ul>

<p>
If an error occurs, a <code class="code">NULL</code> pointer is returned.
</p>
<p>
If no error occurs, the returned pointer will reflect an
allocation aligned to the value of
<code class="constant">GL_MIN_MAP_BUFFER_ALIGNMENT</code> basic machine
units. Subtracting <em class="parameter"><code>offset</code></em> from this
returned pointer will always produce a multiple of the value of
<code class="constant">GL_MIN_MAP_BUFFER_ALIGNMENT</code>.
</p>
<p>
The returned pointer values may not be passed as parameter
values to GL commands. For example, they may not be used to
specify array pointers, or to specify or query pixel or texture
image data; such actions produce undefined results, although
implementations may not check for such behavior for performance
reasons.
</p>
<p>
Mappings to the data stores of buffer objects may have
nonstandard performance characteristics. For example, such
mappings may be marked as uncacheable regions of memory, and in
such cases reading from them may be very slow. To ensure optimal
performance, the client should use the mapping in a fashion
consistent with the values of
<code class="constant">GL_BUFFER_USAGE</code> for the buffer object and
of <em class="parameter"><code>access</code></em>. Using a mapping in a fashion
inconsistent with these values is liable to be multiple orders
of magnitude slower than using normal memory.

<div class="refsect1" id="notes">
<h2>Notes</h2>
<p>
Alignment of the returned pointer is guaranteed only if the
version of the GL version is 4.2 or greater. Also, the
<code class="constant">GL_ATOMIC_COUNTER_BUFFER</code> target is accepted
only if the GL version is 4.2 or greater.
</p>
<p>
The <code class="constant">GL_DISPATCH_INDIRECT_BUFFER</code> and
<code class="constant">GL_SHADER_STORAGE_BUFFER</code> targets are
accepted only if the GL version is 4.3 or greater.

<p>
The <code class="constant">GL_QUERY_BUFFER</code> target is available
only if the GL version is 4.4 or greater.

The <code class="constant">GL_MAP_PERSISTENT_BIT</code> and
<code class="constant">GL_MAP_COHERENT_BIT</code> flags are available
