glDrawTransformFeedbackStream draws primitives of a type specified by mode using a count retrieved from the transform feedback stream specified by stream of the transform feedback object specified by id. Calling glDrawTransformFeedbackStream is equivalent to calling glDrawArrays() with mode as specified, first set to zero, and count set to the number of vertices captured on vertex stream stream the last time transform feedback was active on the transform feedback object named by id.
Calling glDrawTransformFeedback() is equivalent to calling glDrawTransformFeedbackStream with stream set to zero.
GL_INVALID_ENUM is generated if mode is not an accepted value.
GL_INVALID_VALUE is generated if id is not the name of a transform feedback object.
GL_INVALID_VALUE is generated if stream is greater than or equal to the value of GL_MAX_VERTEX_STREAMS.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is currently mapped.
GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.
GL_INVALID_OPERATION is generated if mode is GL_PATCHES and no tessellation control shader is active.
GL_INVALID_OPERATION is generated if
glEndTransformFeedback has never been called while the transform feedback object named by id was bound.
