## Name

glGetQueryiv — return parameters of a query object target

## C Specification

`void glGetQueryiv(` | GLenum target,
| 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`.

`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

`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`. 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`.

## Errors

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