       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       posix_trace_close, posix_trace_open,  posix_trace_rewind	 —  trace  log
       management (TRACING)

       #include <trace.h>

       int posix_trace_close(trace_id_t trid);
       int posix_trace_open(int file_desc, trace_id_t *trid);
       int posix_trace_rewind(trace_id_t trid);

       The posix_trace_close() function shall deallocate the trace log identi‐
       fier indicated by trid, and all of its associated resources.  If	 there
       is no valid trace log pointed to by the trid, this function shall fail.

       The  posix_trace_open() function shall allocate the necessary resources
       and establish the connection between a  trace  log  identified  by  the
       file_desc  argument  and	 a  trace  stream identifier identified by the
       object pointed to by the trid argument. The file_desc  argument	should
       be  a  valid  open file descriptor that corresponds to a trace log. The
       file_desc argument shall be open for reading. The current  trace	 event
       timestamp,  which  specifies the timestamp of the trace event that will
       be read by the next call to posix_trace_getnext_event(), shall  be  set
       to  the	timestamp  of the oldest trace event recorded in the trace log
       identified by trid.

       The posix_trace_open() function shall return a trace stream  identifier
       in  the variable pointed to by the trid argument, that may only be used
       by the following functions:

       posix_trace_close()			posix_trace_get_attr()
       posix_trace_eventid_equal()		posix_trace_get_status()
       posix_trace_eventid_get_name()		posix_trace_getnext_event()
       posix_trace_eventtypelist_getnext_id()	posix_trace_rewind()

       In particular, notice that the operations normally used by a trace con‐
       troller	process,  such	as posix_trace_start(), posix_trace_stop(), or
       posix_trace_shutdown(), cannot be invoked using the trace stream	 iden‐
       tifier returned by the posix_trace_open() function.

       The  posix_trace_rewind()  function shall reset the current trace event
       timestamp, which specifies the timestamp of the trace event  that  will
       be  read	 by the next call to posix_trace_getnext_event(), to the time‐
       stamp of the oldest trace event recorded in the trace log identified by

       Upon  successful	 completion,  these  functions shall return a value of
       zero. Otherwise, they shall return the corresponding error number.

       If successful, the posix_trace_open() function stores the trace	stream
       identifier value in the object pointed to by trid.

       The posix_trace_open() function shall fail if:

       EINTR  The  operation was interrupted by a signal and thus no trace log
	      was opened.

       EINVAL The object pointed to by file_desc  does	not  correspond	 to  a
	      valid trace log.

       The posix_trace_close() and posix_trace_rewind() functions may fail if:

       EINVAL The  object  pointed  to	by trid does not correspond to a valid
	      trace log.

       The following sections are informative.




       The posix_trace_close(), posix_trace_open(),  and  posix_trace_rewind()
       functions may be removed in a future version.
