NAME

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

C SYNOPSIS

       #include <pcp/pmapi.h>

       char *pmDerivedErrStr(void);

       cc ... -lpcp

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.
