<para><function>glGetShaderSource</function> returns the
|
|
concatenation of the source code strings from the shader object
|
|
specified by <parameter>shader</parameter>. The source code
|
|
strings for a shader object are the result of a previous call to
|
|
<citerefentry><refentrytitle>glShaderSource</refentrytitle></citerefentry>.
|
|
The string returned by the function will be null
|
|
terminated.</para>
|
|
|
|
<para><function>glGetShaderSource</function> returns in
|
|
<parameter>source</parameter> as much of the source code string
|
|
as it can, up to a maximum of <parameter>bufSize</parameter>
|
|
characters. The number of characters actually returned,
|
|
excluding the null termination character, is specified by
|
|
<parameter>length</parameter>. If the length of the returned
|
|
string is not required, a value of <constant>NULL</constant> can
|
|
be passed in the <parameter>length</parameter> argument. The
|
|
size of the buffer required to store the returned source code
|
|
string can be obtained by calling
|
|
<citerefentry><refentrytitle>glGetShader</refentrytitle></citerefentry>
|
|
with the value
|
|
<constant>GL_SHADER_SOURCE_LENGTH</constant>.</para>
