NAME

       pmTypeStr, pmTypeStr_r - convert a performance metric type into a string

C SYNOPSIS

       #include <pcp/pmapi.h>

       const char *pmTypeStr(int type);
       char *pmTypeStr_r(int type, char *buf, int buflen);

       cc ... -lpcp

DESCRIPTION

       Given  a  performance  metric  type,  pmTypeStr produces a terse ASCII equivalent, appropriate for use in
       error and diagnostic messages.  The pmTypeStr_r function does the same, but stores the result in a  user-
       supplied buffer buf of length buflen, which should have room for at least 20 bytes.

       The  value  for  type is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3)
       for a particular performance metric.

       Examples are 32 (for type equals PM_TYPE_32), U64 (for type  equals  PM_TYPE_U64),  AGGREGATE  (for  type
       equals PM_TYPE_AGGREGATE), etc.

       The  string  value  result for pmTypeStr is held in a single static buffer, so the returned value is only
       valid until the next call to pmTypeStr.

NOTES

       pmTypeStr returns a pointer to a static buffer and hence is not thread-safe.  Multi-threaded applications
       should use pmTypeStr_r instead.
