+.SH NAME
+posix_trace_attr_destroy,
+posix_trace_attr_init
+\(em destroy and initialize the trace stream attributes object
+(\fBTRACING\fP)
+.SH SYNOPSIS
+.LP
+.nf
+#include <trace.h>
+.P
+int posix_trace_attr_destroy(trace_attr_t *\fIattr\fP);
+int posix_trace_attr_init(trace_attr_t *\fIattr\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIposix_trace_attr_destroy\fR()
+function shall destroy an initialized trace attributes object.
+A destroyed
+.IR attr
+attributes object can be reinitialized using
+\fIposix_trace_attr_init\fR();
+the results of otherwise referencing the object after it
+has been destroyed are undefined.
+.P
+The
+\fIposix_trace_attr_init\fR()
+function shall initialize a trace attributes object
+.IR attr
+with the default value for all of the individual attributes used by a
+given implementation. The read-only
+.IR generation-version
+and
+.IR clock-resolution
+attributes of the newly initialized trace attributes object shall be
+set to their appropriate values (see
+.IR "Section 2.11.1.2" ", " "posix_trace_status_info Structure").
+.P
+Results are undefined if
+\fIposix_trace_attr_init\fR()
+is called specifying an already initialized
+.IR attr
+attributes object.
+.P
+Implementations may add extensions to the trace attributes object
+structure as permitted in the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Chapter 2" ", " "Conformance".
+.P
+The resulting attributes object (possibly modified by setting
+individual attributes values), when used by
+\fIposix_trace_create\fR(),
+defines the attributes of the trace stream created. A single
+attributes object can be used in multiple calls to
+\fIposix_trace_create\fR().
+After one or more trace streams have been created using an attributes
+object, any function affecting that attributes object, including
+destruction, shall not affect any trace stream previously created. An
+initialized attributes object also serves to receive the attributes of
+an existing trace stream or trace log when calling the
+\fIposix_trace_get_attr\fR()
+function.
+.SH "RETURN VALUE"
+Upon successful completion, these functions shall return a value of
+zero. Otherwise, they shall return the corresponding error number.
+.SH ERRORS
+The
+\fIposix_trace_attr_destroy\fR()
+function may fail if:
+.TP
+.BR EINVAL
+The value of
+.IR attr
+is invalid.
+.P
+The
+\fIposix_trace_attr_init\fR()
+function shall fail if:
+.TP
+.BR ENOMEM
+Insufficient memory exists to initialize the trace attributes object.

+.SH "FUTURE DIRECTIONS"
+The
+\fIposix_trace_attr_destroy\fR()
+and
+\fIposix_trace_attr_init\fR()
+functions may be removed in a future version.
