Function Documentation

struct gl_shared_state* _mesa_alloc_shared_state

(

GLcontext *

ctx

)

[read]

Allocate and initialize a shared context state structure.

Initializes the display list, texture objects and vertex programs hash tables, allocates the texture objects. If it runs out of memory, frees everything already allocated before returning NULL.

Returns:

pointer to a gl_shared_state structure on success, or NULL on failure.

void _mesa_free_shared_state	(	GLcontext *	ctx,
		struct gl_shared_state *	shared
	)

Deallocate a shared state object and all children structures.

Parameters:

	ctx	GL context.
	shared	shared state pointer.

Frees the display lists, the texture objects (calling the driver texture deletion callback to free its private data) and the vertex programs, as well as their hash tables.
