            <code class="function">glCreateShaderProgram</code> creates a program object containing compiled and linked
            shaders for a single stage specified by <em class="parameter"><code>type</code></em>. <em class="parameter"><code>strings</code></em>
            refers to an array of <em class="parameter"><code>count</code></em> strings from which to create the shader executables.
       </p><p>
            <code class="function">glCreateShaderProgram</code> is equivalent (assuming no errors are generated) to:
       </p><pre class="programlisting">    const GLuint shader = glCreateShader(type);
    if (shader) {
        glShaderSource(shader, count, strings, NULL);

        if (program) {
            GLint compiled = GL_FALSE;
            glGetShaderiv(shader, GL_COMPILE_STATUS, &amp;compiled);
            glProgramParameteri(program, GL_PROGRAM_SEPARABLE, GL_TRUE);
            if (compiled) {
                glAttachShader(program, shader);
                glLinkProgram(program);

        return program;
    } else {
        return 0;
    }</pre><p>
        The program object created by <code class="function">glCreateShaderProgram</code> has its <code class="constant">GL_PROGRAM_SEPARABLE</code>
        status set to <code class="constant">GL_TRUE</code>.
    </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p>
            <code class="constant">GL_INVALID_ENUM</code> is generated if if <em class="parameter"><code>type</code></em> is not
            an accepted shader type.
        </p><p>
            <code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>count</code></em> is
            negative.
        </p><p>
            Other errors are generated if the supplied shader code fails to compile
            and link, as described for the commands in the pseudocode sequence above,
            but all such errors are generated without any side effects of executing those
            commands.
