+.SH NAME
+posix_trace_get_attr,

+\(em retrieve the trace attributes or trace status
+(\fBTRACING\fP)
+.SH SYNOPSIS
+.LP
+.nf
+#include <trace.h>
+.P
+int posix_trace_get_attr(trace_id_t \fItrid\fP, trace_attr_t *\fIattr\fP);
+int posix_trace_get_status(trace_id_t \fItrid\fP,
+    struct posix_trace_status_info *\fIstatusinfo\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIposix_trace_get_attr\fR()
+function shall copy the attributes of the active trace stream
+identified by
+.IR trid
+into the object pointed to by the
+.IR attr
+argument.
+If the Trace Log option is supported,
+.IR trid
+may represent a pre-recorded trace log.
+.P
+The
+\fIposix_trace_get_status\fR()
+function shall return, in the structure pointed to by the
+.IR statusinfo
+argument, the current trace status for the trace stream identified by
+the
+.IR trid
+argument. These status values returned in the structure pointed to by
+.IR statusinfo
+shall have been appropriately read to ensure that the returned values
+are consistent.
+If the Trace Log option is supported and the
+.IR trid
+argument refers to a pre-recorded trace stream, the status shall be the
+status of the completed trace stream.
+.P
+Each time the
+\fIposix_trace_get_status\fR()
+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
+\fIposix_trace_get_status\fR()
+function shall behave the same as when the option is not supported
+except for the following differences:
+.IP " *" 4
+If the
+.IR trid
+argument refers to a trace stream with log, each time the
+\fIposix_trace_get_status\fR()
+function is used, the log overrun status of the trace stream shall be
+reset to POSIX_TRACE_NO_OVERRUN and the
+.IR flush_error
+status shall be reset to zero immediately after the call completes.
+.IP " *" 4
+If the
+.IR 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.
+.SH "RETURN VALUE"
+Upon successful completion, these functions shall return a value of
+zero. Otherwise, they shall return the corresponding error number.
+.P
+The
+\fIposix_trace_get_attr\fR()
+function stores the trace attributes in the object pointed to by
+.IR attr ,
+if successful.
+.P
+The
+\fIposix_trace_get_status\fR()
+function stores the trace status in the object pointed to by
+.IR statusinfo ,
+if successful.
+.SH ERRORS
+These functions shall fail if:
+.TP
+.BR EINVAL
+The trace stream argument
+.IR trid
+does not correspond to a valid active trace stream or a valid trace
+log.
