+.SH DESCRIPTION
+.de CW
+.ie t \f(CW\\$1\f1\\$2
+.el \fI\\$1\f1\\$2
+..
+Given a performance metric
+.IR type ,
+.B pmTypeStr
+produces a terse ASCII equivalent, appropriate for use in error and diagnostic
+messages.
+The
+.B pmTypeStr_r
+function does the same, but stores the result in a user-supplied buffer
+.I buf
+of length
+.IR buflen ,
+which should have room for at least 20 bytes.
+.PP
+The value for
+.I type
+is typically extracted from a
+.CW pmDesc
+structure, following a call to
+.BR pmLookupDesc (3)
+for a particular performance metric.
+.PP
+Examples are
+.B 32
+(for
+.I type
+equals
+.BR PM_TYPE_32 ),
+.B U64
+(for
+.I type
+equals
+.BR PM_TYPE_U64 ),
+.B AGGREGATE
+(for
+.I type
+equals
+.BR PM_TYPE_AGGREGATE ),
+etc.
+.PP
+The string value result for
+.B pmTypeStr
+is held in a single static buffer, so the returned value is
+only valid until the next call to
+.BR pmTypeStr .
+.SH NOTES
+.B pmTypeStr
+returns a pointer to a static buffer and hence is not thread-safe.
+Multi-threaded applications should use
+.B pmTypeStr_r
+instead.
