glGetTexParameter 3G
glGetTexParameter return texture parameter values

## C Specification

void `glGetTexParameterfv` GLenum target GLenum pname GLfloat * params void `glGetTexParameteriv` GLenum target GLenum pname GLint * params

## Parameters

target

  Specifies the symbolic name of the target texture of the active texture unit. `GL_TEXTURE_2D` and `GL_TEXTURE_CUBE_MAP` are accepted.

pname

  Specifies the symbolic name of a texture parameter. `GL_TEXTURE_MAG_FILTER`, `GL_TEXTURE_MIN_FILTER`, `GL_TEXTURE_WRAP_S`, and `GL_TEXTURE_WRAP_T` are accepted.

params

  Returns the texture parameter.

## Description

`glGetTexParameter` returns in params the value of the texture parameter specified as pname. target defines the target texture of the active texture unit, either `GL_TEXTURE_2D` or `GL_TEXTURE_CUBE_MAP`, to specify two-dimensional or cube-mapped texturing. pname accepts the same symbols as glTexParameter, with the same interpretations:

`GL_TEXTURE_MAG_FILTER`

  Returns the single-valued texture magnification filter, a symbolic constant. The initial value is `GL_LINEAR`.

`GL_TEXTURE_MIN_FILTER`

  Returns the single-valued texture minification filter, a symbolic constant. The initial value is `GL_NEAREST_MIPMAP_LINEAR`.

`GL_TEXTURE_WRAP_S`

  Returns the single-valued wrapping function for texture coordinate s, a symbolic constant. The initial value is `GL_REPEAT`.

`GL_TEXTURE_WRAP_T`

  Returns the single-valued wrapping function for texture coordinate t, a symbolic constant. The initial value is `GL_REPEAT`.

## 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.
