PMTYPESTR(3)              Library Functions Manual              PMTYPESTR(3)

NAME         top

       pmTypeStr,  pmTypeStr_r  -  convert  a performance metric type into a

C SYNOPSIS         top

       #include <pcp/pmapi.h>

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

       cc ... -lpcp

DESCRIPTION         top

       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

       Examples are 32 (for type equals PM_TYPE_32), U64 (for type equals
       PM_TYPE_U64), STRING (for type equals PM_TYPE_STRING), etc.

NOTES         top

       Both of these functions are safe to call from threaded contexts.
