# glGetQueryIndexediv

return parameters of an indexed query object target

## C Specification

                    void glGetQueryIndexediv
                    GLenum target
                    GLuint index
                    GLenum pname
                    GLint * params

## Parameters

`target`

  Specifies a query object target. Must be `GL_SAMPLES_PASSED`, `GL_ANY_SAMPLES_PASSED`, `GL_ANY_SAMPLES_PASSED_CONSERVATIVE` `GL_PRIMITIVES_GENERATED`, `GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN`, `GL_TIME_ELAPSED`, or `GL_TIMESTAMP`.

`index`

  Specifies the index of the query object target.

`pname`

  Specifies the symbolic name of a query object target parameter. Accepted values are `GL_CURRENT_QUERY` or `GL_QUERY_COUNTER_BITS`.

`params`

  Returns the requested data.

## Description

`glGetQueryIndexediv` returns in `params` a selected parameter of the indexed query object target specified by `target` and `index`. `index` specifies the index of the query object target and must be between zero and a target-specific maxiumum.

`pname` names a specific query object target parameter. When `pname` is `GL_CURRENT_QUERY`, the name of the currently active query for the specified `index` of `target`, or zero if no query is active, will be placed in `params`. If `pname` is `GL_QUERY_COUNTER_BITS`, the implementation-dependent number of bits used to hold the result of queries for `target` is returned in `params`.

## Notes

The target `GL_ANY_SAMPLES_PASSED_CONSERVATIVE` is available only if the GL version is 4.3 or greater.

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

Calling glGetQueryiv is equivalent to calling `glGetQueryIndexediv` with `index` set to zero.

## Errors

`GL_INVALID_ENUM` is generated if `target` or `pname` is not an accepted value.

`GL_INVALID_VALUE` is generated if `index` is greater than or equal to the `target`-specific maximum.
