## Name

glGetMinmaxParameterfv, glGetMinmaxParameteriv — get minmax parameters

## C Specification

`void `glGetMinmaxParameterfv`` | `(` | `GLenum `target`, GLenum `pname`, GLfloat *`params`);`
`void `glGetMinmaxParameteriv`` | `(` | `GLenum `target`, GLenum `pname`, GLint *`params`);`

## Python Specification

``glGetMinmaxParameterfv`` | `(` | ``target`, `pname`) → `params``
``glGetMinmaxParameteriv`` | `(` | ``target`, `pname`) → `params``

## Parameters

`target`
  Must be `GL_MINMAX`.
`pname`
  The parameter to be retrieved. Must be one of `GL_MINMAX_FORMAT` or `GL_MINMAX_SINK`.
`params`
  A pointer to storage for the retrieved parameters.

## Description

`glGetMinmaxParameter` retrieves parameters for the current minmax table by setting `pname` to one of the following values:

Parameter | Description
`GL_MINMAX_FORMAT` | Internal of minmax table
`GL_MINMAX_SINK` | Value of the `sink` parameter

## Notes

`glGetMinmaxParameter` is present only if `GL_ARB_imaging` is returned when `glGetString` is called with an argument of `GL_EXTENSIONS`.

## Errors

`GL_INVALID_ENUM` is generated if `target` is not `GL_MINMAX`.

`GL_INVALID_ENUM` is generated if `pname` is not one of the allowable values.

`GL_INVALID_OPERATION` is generated if `glGetMinmaxParameter` is executed between the execution of `glBegin` and the corresponding execution of `glEnd`.
