<para>

<function>glClearBufferData</function> fills the entirety of a buffer object's
|
|
data store with data from client memory. Data, initially supplied in a format
|
|
specified by <parameter>format</parameter> in data type <parameter>type</parameter> is
|
|
read from the memory address given by <parameter>data</parameter> and converted into
|
|
the internal representation given by <parameter>internalforamt</parameter>.
|

This converted data is then replicated throughout the buffer object's
|
|
data store.

</para>

<para>

If <parameter>data</parameter> is NULL, then the buffer's data store

is filled with zeros.
