glGetQueryiv 3G
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_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

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.
