+/**
+ * @file
+ *
+ * @section DESCRIPTION
+ *
+ * These functions provide a portable implementation of the common (but not
+ * yet universal) asprintf & vasprintf routines to allocate a buffer big
+ * enough to sprintf the arguments to.  The XNF variants terminate the server
+ * if the allocation fails.
