/** @file negative-getactiveuniformblockiv.c
*
* From the GL_ARB_uniform_buffer_object spec:
*
* "<uniformBlockIndex> is an active uniform block index of
* <program>. If <uniformBlockIndex> is greater than or equal to
* the value of ACTIVE_UNIFORM_BLOCKS, or is not the index of an
* active uniform block in <program>, the error INVALID_VALUE is
* generated.
*
* If no error occurs, the uniform block parameter(s) specified
* by <pname> are returned in <params>. Otherwise, nothing will
* be written to <params>.
*
* The error INVALID_VALUE is generated by GetUniformIndices,
* GetActiveUniformsiv, GetActiveUniformName,
* GetUniformBlockIndex, GetActiveUniformBlockiv,
* GetActiveUniformBlockName, and UniformBlockBinding if
* <program> is not a value generated by GL.
*
* The error INVALID_ENUM is generated by GetActiveUniformsiv and
* GetActiveUniformBlockiv if <pname> is not one of the accepted
* values."
