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
