18 Given a performance metric type, pmTypeStr produces a terse ASCII
19 equivalent, appropriate for use in error and diagnostic messages. The
20 pmTypeStr_r function does the same, but stores the result in a user-
21 supplied buffer buf of length buflen, which should have room for at
22 least 20 bytes.
23
24 The value for type is typically extracted from a pmDesc structure, fol‐
25 lowing a call to pmLookupDesc(3) for a particular performance metric.
26
27 Examples are 32 (for type equals PM_TYPE_32), U64 (for type equals
28 PM_TYPE_U64), STRING (for type equals PM_TYPE_STRING), etc.
29
31 Both of these functions are safe to call from threaded contexts.
