Function Documentation

void _mesa_vector4f_alloc	(	GLvector4f *	v,
		GLbitfield	flags,
		GLuint	count,
		GLuint	alignment
	)

Initialize GLvector objects and allocate storage.

Parameters:

	v	the vector object
	flags	bitwise-OR of VEC_* flags
	count	number of elements to allocate in vector
	alignment	desired memory alignment for the data (in bytes)

void _mesa_vector4f_clean_elem	(	GLvector4f *	vec,
		GLuint	count,
		GLuint	elt
	)

Given a vector [count][4] of floats, set all the [][elt] values to 0 (if elt = 0, 1, 2) or 1.0 (if elt = 3).

void _mesa_vector4f_free

(

GLvector4f *

v

)

Vector deallocation.

Free whatever memory is pointed to by the vector's storage field if the VEC_MALLOC flag is set. DO NOT free the GLvector object itself, though.

void _mesa_vector4f_init	(	GLvector4f *	v,
		GLbitfield	flags,
		GLfloat *	storage[4]
	)

Initialize GLvector objects.

Parameters:

	v	the vector object to initialize.
	flags	bitwise-OR of VEC_* flags
	storage	pointer to storage for the vector's data

void _mesa_vector4f_print	(	const GLvector4f *	v,
		const GLubyte *	cullmask,
		GLboolean	culling
	)

For debugging.
