void GLAPIENTRY _mesa_ClientActiveTextureARB

(

GLenum

target

)

void _mesa_copy_texture_state	(	const GLcontext *	src,
		GLcontext *	dst
	)

Used by glXCopyContext to copy texture state from one context to another.

void _mesa_free_texture_data

(

GLcontext *

ctx

)

Free dynamically-allocted texture data attached to the given context.

static INLINE struct gl_texture_unit* _mesa_get_current_tex_unit

(

GLcontext *

ctx

)

[static, read]

Return pointer to current texture unit.

This the texture unit set by glActiveTexture(), not glClientActiveTexture().

GLboolean _mesa_init_texture

(

GLcontext *

ctx

)

Initialize texture state for the given context.

void _mesa_print_texunit_state	(	GLcontext *	ctx,
		GLuint	unit
	)

void _mesa_update_default_objects_texture

(

GLcontext *

ctx

)

Update the default texture objects in the given context to reference those specified in the shared state and release those referencing the old shared state.

void _mesa_update_texture	(	GLcontext *	ctx,
		GLuint	new_state
	)

Update texture-related derived state.
