17  These functions work like the standard C printf functions, except that a
18  reduced set of formatting operations are supported.
19  
20  In particular: formatting of long long values is not supported.  Formatting of
21  floating-point values is done as though with %A even when other formats like %f
22  are specified.

24  .SH REALTIME CONSIDERATIONS
25  May be called from user, init/cleanup, and realtime code.
