+rmr_get_srcip 
+ 
+SYNOPSIS 
+-------------------------------------------------------------------------------------------- 
+ 
+ 
+:: 
+  
+ #include <rmr/rmr.h>
+ unsigned char* rmr_get_srcip( rmr_mbuf_t* mbuf, unsigned char* dest )
+ 
+ 
+ 
+DESCRIPTION 
+-------------------------------------------------------------------------------------------- 
+ 
+The rmr_get_srcip function will copy the *source IP address* 
+from the message to a buffer (dest) supplied by the user. In 
+an RMr message, the source IP address is the sender's 
+information that is used for return to sender function calls; 
+this function makes it available to the user application. The 
+address is maintained as IP:port where *IP* could be either 
+an IPv6 or IPv4 address depending on what was provided by the 
+sending application. 
+ 
+The maximum size allowed by RMr is 64 bytes (including the 
+nil string terminator), so the user must ensure that the 
+destination buffer given is at least 64 bytes. The user 
+application should use the RMr constant RMR_MAX_SRC to ensure 
+that the buffer supplied is large enough, and to protect 
+against future RMr enhancements which might increase the 
+address buffer size requirement. 
+ 
+RETURN VALUE 
+-------------------------------------------------------------------------------------------- 
+ 
+On success, a pointer to the destination buffer is given as a 
+convenience to the user programme. On failure, a nil pointer 
+is returned and the value of errno is set. 
+ 
+ERRORS 
+-------------------------------------------------------------------------------------------- 
+ 
+If an error occurs, the value of the global variable errno 
+will be set to one of the following with the indicated 
+meaning. 
+ 
+ 
+ 
+EINVAL 
+   
+  The message, or an internal portion of the message, was 
+  corrupted or the pointer was invalid.
