.SH DESCRIPTION
This macro should be used if you want to setup callback function fired while connection link initiating, this call shouldn't be ignored since it setups the RPC channels tree structure used within the connection link.
.br
This macro will set on
.B c
connections link set callback
.B f 
which is a function pointer of the type:
.br
.sp
.B typedef usrtc_t* (*rpcvalidate_t)(conn_t *);
.br
.sp
It will pass a pointer to the connection link initiating now. Link isn't set fully at this moment and doesn't pass any messages and don't works with channel's operations. To pass initiation to the next stage this function should return 
a valid pointer to the 
.B usrtc_t
structure, this structure must be created with 
.B sxmp_rpclist_init
,
.B sxmp_rpclist_add
,
.B sxmp_rpclist_add_function
 series functions.

The returned value will be not handled by library and you should care about freeing it in your application.
