NAME

SYNOPSIS

9         #include <xpa.h>

DESCRIPTION

15       Server routines have  access to information about the XPA being called
16       via the following macros (each of which takes the xpa handle as an
17       argument):
18
19         macro                 explanation
20         ------                -----------
21         xpa_class             class of this xpa
22         xpa_name              name of this xpa
23         xpa_method            method string (inet or local connect info)
24         xpa_cmdfd             fd of command socket
25         xpa_datafd            fd of data socket
26         xpa_sendian           endian-ness of server ("little" or "big")
27         xpa_cendian           endian-ness of client ("little" or "big"
28
29       The argument to these macros is the call_data pointer that is passed to
30       the server procedure.  This pointer should be type case to XPA in the
31       server routine:
32
33         XPA xpa = (XPA)call_data;
34
35       The most important of these macros is xpa_datafd().  A server routine
36       that sets "fillbuf=false" in receive_mode or send_mode can use this
37       macro to perform I/O directly to/from the client, rather than using
38       buf.
39
40       The xpa_cendian and xpa_sendian macros can be used together to
41       determine if the data transferred from the client is byte swapped with
42       respect to the server. Values for these macros are: "little", "big", or
43       "?".  In order to do a proper conversion, you still need to know the
44       format of the data (i.e., byte swapping is dependent on the size of the
45       data element being converted).
