19 .Nd Linux-compatible timer notification facility
24 is a Linux-borne facility for creating POSIX timers and
25 receiving their subsequent events via a file descriptor.
26 The facility itself is arguably unnecessary:
27 portable code can either use the timeout value present in
30 or -- if this is deemed of unacceptably poor resolution -- create a POSIX timer
33 and use the resulting signal to induce an
35 to polling threads. (For code that need not be
38 signal notification allows for explicit, event-oriented timer notification to be
39 sent to a specified port; see
41 for details.) This facility therefore exists only to accommodate Linux-borne
42 applications and binaries; it is compatible with its Linux antecedent in both
43 binary interface and in semantics.
