PMSEMSTR(3)                Library Functions Manual                PMSEMSTR(3)

NAME
       pmSemStr, pmSemStr_r - convert a performance metric semantic into a
       string

C SYNOPSIS
       #include <pcp/pmapi.h>

       const char *pmSemStr(int sem);
       char *pmSemStr_r(int sem, char *buf, int buflen);

       cc ... -lpcp

DESCRIPTION
       Given a performance metric semantic, pmSemStr produces a terse ASCII
       equivalent, appropriate for use in error and diagnostic messages.  The
       pmSemStr_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 sem is typically extracted from a pmDesc structure,
       following a call to pmLookupDesc(3) for a particular performance
       metric.

       Examples are counter (for sem equals PM_SEM_COUNTER), discrete (for sem
       equals PM_SEM_DISCRETE), instant (for sem equals PM_SEM_INSTANT), etc.

NOTES
       Both of these routines are safe to call from threaded applications.
