PMTYPESTR(3) Library Functions Manual PMTYPESTR(3)
pmTypeStr, pmTypeStr_r - convert a performance metric type into a string
#include <pcp/pmapi.h> const char *pmTypeStr(int type); char *pmTypeStr_r(int type, char *buf, int buflen); cc ... -lpcp
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), STRING (for type equals PM_TYPE_STRING), etc.
Both of these functions are safe to call from threaded contexts.
