al_transpose_transform(3)  Library Functions Manual  al_transpose_transform(3)

NAME
       al_transpose_transform -	Allegro	5 API

SYNOPSIS
	      #include <allegro5/allegro.h>

	      void al_transpose_transform(ALLEGRO_TRANSFORM *trans)

DESCRIPTION
       Transposes the matrix of	the given transform.  This can be used for in-
       versing a rotation transform.  For example:

	      al_build_camera_transform(camera,	0, 0, 0, x, y, z, xu, yu, zu)
	      al_copy_transform(inverse, camera)
	      al_transpose_transform(camera)
	      // Now "inverse" will be a transformation	rotating in the	opposite
	      // direction from	"camera". Note that this only works if the camera
	      // position is 0/0/0 as in the example.
