FastCGI with NSPR

Hello,

I would like to create a FastCGI program using NSPR.
The FastCGI Specification (http://www.fastcgi.com/devkit/doc/fcgi-
spec.htm) says:

  Accepting Transport Connections:
    A FastCGI application calls accept() on the socket referred to by
file descriptor FCGI_LISTENSOCK_FILENO to accept a new transport
connection.

( #define FCGI_LISTENSOCK_FILENO 0 )


It seems that it is not possible for  PR_Accept  to accept something
else that a  PRFileDesc  .
And I did not see any functions to convert a native file descriptor
into a RP file descriptor.


do i miss something obvious ?  or can I use a workaround ?


Thanks.

Franck.
