specifies the parameter to be retrieved; must be one of
GL_VERTEX_ATTRIB_ARRAY_BUFFER_BINDING
,
GL_VERTEX_ATTRIB_ARRAY_ENABLED
,
GL_VERTEX_ATTRIB_ARRAY_SIZE
,
GL_VERTEX_ATTRIB_ARRAY_STRIDE

GL_VERTEX_ATTRIB_ARRAY_TYPE
,
GL_VERTEX_ATTRIB_ARRAY_NORMALIZED
,
GL_VERTEX_ATTRIB_ARRAY_INTEGER
,
or
GL_VERTEX_ATTRIB_ARRAY_DIVISOR.
GL_CURRENT_VERTEX_ATTRIB
returns the current vertex
attribute as specified by
glEnableVertexAttribArray
, and
the other parameters are values specified when the vertex
attribute pointer is specified by calling
glVertexAttribPointer.
specifies an array of the appropriate type for storing the
returned parameter values.

OpenGL ES 3.0 texture objects store a texture's image data, along with
settings describing how the texels in the image should be sampled. The
texture filter state, which includes the minification and magnification texture
filters and texture-coordinate wrap modes, can be queried from the currently
bound texture object. The following call retrieves the texture filter settings:
void
glGetTexParameterfv
(GLenum
target
, GLenum
pname
,
GLfloat *
params
)
void
glGetTexParameteriv
(GLenum
target
, GLenum
pname
,
GLint *
params
)
specifies the texture target; can either be
GL_TEXTURE_2D,
GL_TEXTURE_2D_ARRAY, GL_TEXTURE_3D
, or
GL_TEXTURE_CUBE_MAP
target
specifies the texture filter parameter to be retrieved; may be
GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_COMPARE_FUNC
,
GL_TEXTURE_COMPARE_MODE
,
GL_TEXTURE_MAG_FILTER
,
GL_TEXTURE_IMMUTABLE_FORMAT
,
GL_TEXTURE_MAX_LEVEL
,
GL_TEXTURE_MAX_LOD
,
GL_TEXTURE_MIN_FILTER
,
GL_TEXTURE_MIN_LOD
,
GL_TEXTURE_SWIZZLE_R
