## C Specification

                    void glGetQueryiv
                    GLenum target
                    GLenum pname
                    GLint * params

## Parameters

`target`

  Specifies a query object target. Must be `GL_ANY_SAMPLES_PASSED`, `GL_ANY_SAMPLES_PASSED_CONSERVATIVE`, or `GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN`.

  Specifies the symbolic name of a query object target parameter. Must be `GL_CURRENT_QUERY`.

`params`

  Returns the requested data.

## Description

`glGetQueryiv` returns in `params` a selected parameter of the query object target specified by `target`.

`pname` names a specific query object target parameter. When `pname` is `GL_CURRENT_QUERY`, the name of the currently active query for `target`, or zero if no query is active, will be placed in `params`.

## Notes

If an error is generated, no change is made to the contents of `params`.

## Errors
