+.SH DESCRIPTION
+The
+\fIposix_trace_attr_getclockres\fR()
+function shall copy the clock resolution of the clock used to generate
+timestamps from the
+.IR clock-resolution
+attribute of the attributes object pointed to by the
+.IR attr
+argument into the structure pointed to by the
+.IR resolution
+argument.
+.P
+The
+\fIposix_trace_attr_getcreatetime\fR()
+function shall copy the trace stream creation time from the
+.IR creation-time
+attribute of the attributes object pointed to by the
+.IR attr
+argument into the structure pointed to by the
+.IR createtime
+argument. The
+.IR creation-time
+attribute shall represent the time of creation of the trace stream.
+.P
+The
+\fIposix_trace_attr_getgenversion\fR()
+function shall copy the string containing version information from the
+.IR generation-version
+attribute of the attributes object pointed to by the
+.IR attr
+argument into the string pointed to by the
+.IR genversion
+argument. The
+.IR genversion
+argument shall be the address of a character array which can store at
+least
+{TRACE_NAME_MAX}
+characters.
+.P
+The
+\fIposix_trace_attr_getname\fR()
+function shall copy the string containing the trace name from the
+.IR trace-name
+attribute of the attributes object pointed to by the
+.IR attr
+argument into the string pointed to by the
+.IR tracename
+argument. The
+.IR tracename
+argument shall be the address of a character array which can store at
+least
+{TRACE_NAME_MAX}
+characters.
+.P
+The
+\fIposix_trace_attr_setname\fR()
+function shall set the name in the
+.IR trace-name
+attribute of the attributes object pointed to by the
+.IR attr
+argument, using the trace name string supplied by the
+.IR tracename
+argument. If the supplied string contains more than
+{TRACE_NAME_MAX}
+characters, the name copied into the
+.IR trace-name
+attribute may be truncated to one less than the length of
+{TRACE_NAME_MAX}
+characters. The default value is a null string.
+.SH "RETURN VALUE"
+Upon successful completion, these functions shall return a value of
+zero. Otherwise, they shall return the corresponding error number.
+.P
+If successful, the
+\fIposix_trace_attr_getclockres\fR()
+function stores the
+.IR clock-resolution
+attribute value in the object pointed to by
+.IR resolution .
+Otherwise, the content of this object is unspecified.
+.P
+If successful, the
+\fIposix_trace_attr_getcreatetime\fR()
+function stores the trace stream creation time in the object pointed to
+by
+.IR createtime .
+Otherwise, the content of this object is unspecified.
+.P
+If successful, the
+\fIposix_trace_attr_getgenversion\fR()
+function stores the trace version information in the string pointed to
+by
+.IR genversion .
+Otherwise, the content of this string is unspecified.
+.P
+If successful, the
+\fIposix_trace_attr_getname\fR()
+function stores the trace name in the string pointed to by
+.IR tracename .
+Otherwise, the content of this string is unspecified.
+.SH ERRORS
+The
+\fIposix_trace_attr_getclockres\fR(),
+\fIposix_trace_attr_getcreatetime\fR(),
+\fIposix_trace_attr_getgenversion\fR(),
+and
+\fIposix_trace_attr_getname\fR()
+functions may fail if:
+.TP
