NAME

       PAPIf_hl_read - Reads and stores hardware events inside of an instrumented code region.

SYNOPSIS

Detailed Description

       Fortran Prototype:
           #include <fpapi.h>
           int PAPIf_hl_read( C_STRING region, C_INT check )

       Parameters
           region -- a unique region name corresponding to PAPIf_hl_region_begin

       Return values
           PAPI_OK
           PAPI_ENOTRUN -- EventSet is currently not running or could not determined.
           PAPI_ESYS -- A system or C library call failed inside PAPI, see the errno variable.
           PAPI_EMISC -- PAPI has been deactivated due to previous erros.
           PAPI_ENOMEM -- Insufficient memory.

       PAPIf_hl_read reads hardware events and stores them internally inside of an instrumented code region.
       Assumes that PAPIf_hl_region_begin was called before.

       Example:

       integer retval

       call PAPIf_hl_region_begin("computation", retval)
       if ( retval .NE. PAPI_OK ) then
           write (*,*) "PAPIf_hl_region_begin failed!"
       end if

       !do some computation here

       call PAPIf_hl_read("computation", retval)
       if ( retval .NE. PAPI_OK ) then
           write (*,*) "PAPIf_hl_read failed!"
       end if

       !do some computation here

       call PAPIf_hl_region_end("computation", retval)
       if ( retval .NE. PAPI_OK ) then
           write (*,*) "PAPIf_hl_region_end failed!"
       end if
