## 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 format of minmax table
`GL_MINMAX_SINK` | Value of the sink parameter

## Notes

`glGetMinmaxParameter` is present only if `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.
