NAME
       pmDerivedErrStr - return error message from failure to parse derived
       metric definition

C SYNOPSIS
       #include <pcp/pmapi.h>

       char *pmDerivedErrStr(void);

DESCRIPTION
       When pmRegisterDerived(3) is called to add a new derived metric
       definition and an error occurs, pmDerivedErrStr may be called to return
       the associated error message.

       The pmRegisterDerivedMetric interface provides a convenience wrapper
       around both pmRegisterDerived and pmDerivedErrStr.
