glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, Verts);
glNormalPointer(GL_FLOAT, 0, Normals);
glTexCoordPointer(2, GL_FLOAT, 0, Coords);
glColor4f ( 1,1,1,1 );
glLockArraysEXT(0, (GLsizei)VertsNUM 3);
glDrawElements(GL_TRIANGLES, FacesNUM3, GL_UNSIGNED_INT, Faces);
glUnlockArraysEXT();

	glDisableClientState(GL_VERTEX_ARRAY);
	glDisableClientState(GL_NORMAL_ARRAY);
	glDisableClientState(GL_TEXTURE_COORD_ARRAY);

Verts is a pointer to an array of float[3], as well is Normals, Coords to float[2] and faces defines an array of int[3], defines triangles as entries in Verts; VertsNUM is a number of vertices, but remember that it is three times more entries than verices.
