Searched, but didn’t find any note about it here.
glext.h @ http://oss.sgi.com/projects/ogl-sample/registry/ is missing glGetShaderiv !
Why is that? Did i miss something?
(As i’m using my automated tool to create the extension-checking-attaching-orgy … i’m not really interested to add it myself 
)
glGetShaderiv is an OpenGL 2.0 function.
The glext.h on that page supports up to version 1.5 and glGetShader was not in the GL_ARB_shader_objects spec.
I see. But what is used for detecting filures (compiling, linking …) then?
edit: nevermind. Found ValidateProgramARB(). 
That won’t get you far. Check these functions:
// Shader compiled?
glGetObjectParameterivARB(object, GL_OBJECT_COMPILE_STATUS_ARB, &compiled);
// Program linked?
glGetObjectParameterivARB(program, GL_OBJECT_LINK_STATUS_ARB, &linked);
// Read info log in either case:
glGetObjectParameterivARB(object, GL_OBJECT_INFO_LOG_LENGTH_ARB, &maxLength);
// malloc infoLog here. This call fill it:
glGetInfoLogARB(object, maxLength, &length, infoLog);
