The Low Level API

The following functions represent the low level portion of the
PerfAPI. These functions provide greatly increased efficiency and
functionality over the high level API presented in the next
section. All of the following functions are callable from both C and
Fortran except where noted. As mentioned in the introduction, the low
level API is only as powerful as the component upon which it is
built. Thus some features may not be available on every platform. The
converse may also be true, that more advanced features may be
available and defined in the header file.  The user is encouraged to
read the documentation carefully.  */
