%%%Little modif to connect the Particle Effect to a mesh object :

//
/* Function: M_Particle_New /
/ Python equivalent: Blender.Effect.Particle.New /
/ Description : Create a particle effect and add a link /
/ to the given Object mesh /
/ Data : String mesh object name /
/ Return : pyobject particle */
//

A new procedure from scratch to get the particles locations as a python list
of 3D coordinates :

//
/* Function: GetParticlesLoc /
/ Python equivalent: Blender.Effect.Particle.GetParticlesLoc /
/ Description: Get the current location of each particle /
/ and return a list of 3D coords /
/ Data: String object name, int particle effect number, /
/ float currentframe /
/ Return: One python list of python lists of 3D coords */
//

They seem to work correctly on a blender compilation made with cygwin .
A script to test :

PATCH to the Particle submodule of the python API
To get particles location .

Effect.Particle.New(objectName)
return a particle effect linked to effect list of the mesh object
pointed by the namObject

Effect.Particle.GetParticlesLoc(objectName,effectNumber,frame)
return a list of all particles positions :
x0,y0,z0],[x1,y1,z1],...[xn,yn,zn

example of use :

import Blender
from Blender import Effect, Object,Scene, Mathutils

OBJMAT=Mathutils.Matrix(Object.Get('Cube').getMatrix())

PART=Effect.Particle.New('Cube')
PART.setNormfac(0.5)

PART.setRandfac(0.01)

PART.setTotpart(100)
PART.setFlag(9)
Blender.Window.RedrawAll()

PARTLOC=Effect.Particle.GetParticlesLoc('Cube',0,50)

SC=Scene.getCurrent()
for e in PARTLOC :

VEC=Mathutils.Vector([e- ,e- ,e- ,1.0])
VEC=OBJMAT*VEC

 emp=Object.New('Empty')
 SC.link(emp)

#emp.setLocation(VEC- [x],VEC- [x],VEC[2])

 emp.setLocation(e)

Blender.Window.RedrawAll()
