NAME

       QmcDesc - container for a metric description

C++ SYNOPSIS

       #include <QmcDesc.h>

       CC ... -lqmc -lpcp

DESCRIPTION

       A QmcDesc object is a container for a metric descriptor (pmDesc, see PMAPI(3)) and units.

CONSTRUCTORS & DESTRUCTOR

       ~QmcDesc();
           Destructor.

       QmcDesc(pmID pmid);
           Construct  a  container  for the descriptor for pmid.  The descriptor is obtained from
           the current PMAPI(3) context using pmLookupDesc(3).

DESCRIPTION

       int status() const;
           A status less than zero indicates that the  descriptor  could  not  be  obtained,  the
           PMAPI(3) error is encoded in the result.

       pmID id() const;
           Return the pmID for this descriptor.

       pmDesc desc() const;
           Return a copy of the actual metric descriptor.

       const pmDesc *descPtr() const;
           Return a pointer to the actual descriptor to avoid using a pointer to a temporary.

UNITS

       const QString &units() const;
           The complete unit string for this descriptor.

       const QString &abvUnits() const;
           The unit string using abbreviations.

       bool useScaleUnits() const;
           Returns true if the units have been set by a call to QmcDesc::setScaleUnits.

       const pmUnits &scaleUnits() const;
           Return the scaling units for this descriptor.

       void setScaleUnits(const pmUnits &units);
           Set the scaling units for this descriptor.

SEE ALSO

       PMAPI(3), QMC(3), pmflush(3), pmLookupDesc(3) and pmprintf(3).

DIAGNOSTICS

       Error   messages  are  generated  using  pmprintf(3)  but  are  not  flushed.  It  is  the
       responsibility of the user to call pmflush(3) to output any messages.

       Additional diagnostics may be activated by adding the option pmc to the  global  debugging
       specification, as described in pmSetDebug(3).
