POSIX_TRACE_GET_ATTR(P)                                POSIX_TRACE_GET_ATTR(P)



NAME
       posix_trace_get_attr,  posix_trace_get_status  -  retrieve  the trace attributes or
       trace status (TRACING)

SYNOPSIS
       #include <trace.h>

       int posix_trace_get_attr(trace_id_t trid, trace_attr_t *attr);
       int posix_trace_get_status(trace_id_t trid,
              struct posix_trace_status_info *statusinfo);


DESCRIPTION
       The posix_trace_get_attr() function shall copy the attributes of the  active  trace
       stream identified by trid into the object pointed to by the attr argument.   If the
       Trace Log option is supported, trid may represent a pre-recorded trace log.

       The posix_trace_get_status() function shall return, in the structure pointed to  by
       the  statusinfo  argument, the current trace status for the trace stream identified
       by the trid argument. These status values returned in the structure pointed  to  by
       statusinfo  shall  have  been appropriately read to ensure that the returned values
       are consistent.    If the Trace Log option  is  supported  and  the  trid  argument
       refers  to  a pre-recorded trace stream, the status shall be the status of the com-
       pleted trace stream.

       Each time the posix_trace_get_status() function is used, the overrun status of  the
       trace  stream  shall  be reset to POSIX_TRACE_NO_OVERRUN immediately after the call
       completes.    If the Trace Log option is  supported,  the  posix_trace_get_status()
       function  shall  behave the same as when the option is not supported except for the
       following differences:

        * If the trid  argument  refers  to  a  trace  stream  with  log,  each  time  the
          posix_trace_get_status()  function  is used, the log overrun status of the trace
          stream shall be reset to POSIX_TRACE_NO_OVERRUN and the flush_error status shall
          be reset to zero immediately after the call completes.


        * If  the trid argument refers to a pre-recorded trace stream, the status returned
          shall be the status of the completed trace stream and the status values  of  the
          trace stream shall not be reset.


RETURN VALUE
       Upon  successful  completion,  these functions shall return a value of zero. Other-
       wise, they shall return the corresponding error number.

       The posix_trace_get_attr() function stores  the  trace  attributes  in  the  object
       pointed to by attr, if successful.

       The posix_trace_get_status() function stores the trace status in the object pointed
       to by statusinfo, if successful.

ERRORS
       These functions shall fail if:

       EINVAL The trace stream argument trid does not correspond to a valid  active  trace
              stream or a valid trace log.
