Martin Peres
martin.peres at linux.intel.com
Thu Feb 26 07:41:23 PST 2015
v2: review from Tapani
- add the copyright for Intel
- add some documentation
- set the minimum GL version to 2.0
- use piglit_build_simple_program_unlinked

+/** @file gettransformfeedback.c
+ * Simple transform feedback test drawing GL_POINTS and checking that all the
+ * state is well reported by the GetTransformFeedback*() functions.
+ *
+ * Greatly inspired from ext_transform_feedback/points.c.
+ *
+ * From OpenGL 4.5, section 22.4 "Transform Feedback State Queries", page 552:
+ *
+ * "void GetTransformFeedbackiv(uint xfb, enum pname, int *param);
+ * void GetTransformFeedbacki v(uint xfb, enum pname, uint index, int *param);
+ * void GetTransformFeedbacki64 v(uint xfb, enum pname,uint index,
+ * int64 *param);
+ *
+ * xfb must be zero, indicating the default transform feedback object, or the
+ * name of an existing transform feedback object. pname must be one of the
+ * tokens listed in table 23.48, depending on the command name as shown in the
+ * errors section below. For indexed state, index is the index of the transform
+ * feedback stream. param is the address of a variable to receive the result of
+ * the query.
+ *
+ * Errors
+ * An INVALID_OPERATION error is generated by GetTransformFeedback* if xfb is
+ * not zero or the name of an existing transform feedback object.
+ * An INVALID_ENUM error is generated by GetTransformFeedbackiv if pname is not
+ * TRANSFORM_FEEDBACK_PAUSED or TRANSFORM_FEEDBACK_ACTIVE.
+ * An INVALID_ENUM error is generated by GetTransformFeedbacki v if pname is
+ * not TRANSFORM_FEEDBACK_BUFFER_BINDING.
+ * An INVALID_ENUM error is generated by GetTransformFeedbacki64 v if pname is
+ * not TRANSFORM_FEEDBACK_BUFFER_START or TRANSFORM_FEEDBACK_BUFFER_SIZE.
+ * An INVALID_VALUE error is generated by GetTransformFeedbacki v and
+ * GetTransformFeedbacki64 v if index is greater than or equal to the number
+ * of binding points for transform feedback, as described in section 6.7.1."
