Header files

• Header files for Fortran: Every Fortran file containing any of the instrumentation routines below has to include the line:

    #include "f_hpm.h"
  

  This is not Fortran and needs to be interpreted by the preprocessor. See here for details on how to invoke the preprocessor.

• Header files for C: Every C file containing any of the instrumentation routines below has to use the line

    #include "libhpm.h"
  

  which is standard C. No preprocessor is needed unless your code does need it anyway.
