SYNOPSIS

C Interface

#include <papi.h> 

const PAPI_exe_info_t *PAPI_get_executable_info(void); 

Fortran Interface

#include fpapi.h 

PAPIF_get_exe_info(C_STRING fullname, C_STRING name, 

       C_LONG_LONG text_start, C_LONG_LONG text_end, 

       C_LONG_LONG data_start, C_LONG_LONG data_end, 

       C_LONG_LONG bss_start,  C_LONG_LONG bss_end, C_INT check) 

DESCRIPTION

In C, this function returns a pointer to a structure containing information about the current program. In Fortran, the fields of the structure are returned explicitly.

ARGUMENTS

The following arguments are implicit in the structure returned by the C function, or explicitly returned by Fortran.

fullname -- fully qualified path + filename of the executable

name -- filename of the executable with no path information

text_start, text_end -- Start and End addresses of program text segment

data_start, data_end -- Start and End addresses of program data segment

bss_start, bss_end -- Start and End addresses of program bss segment

RETURN VALUES

On success, the C function returns a non-NULL pointer, and the Fortran function returns PAPI_OK.
On error, NULL is returned by the C function, and a non-zero error code is returned by the Fortran function.

ERRORS

PAPI_EINVAL
  One or more of the arguments is invalid.

EXAMPLE


const PAPI_exe_info_t *prginfo = NULL;
        
if ((prginfo = PAPI_get_executable_info()) == NULL)
  exit(1);

printf("Path+Program: %s0,exeinfo->fullname); printf("Program: %s0,exeinfo->address_info.name); printf("Text start: %p, Text end: %p0,exeinfo->address_info.text_start,exeinfo->address_info.text_end); printf("Data start: %p, Data end: %p0,exeinfo->address_info.data_start,exeinfo->address_info.data_end); printf("Bss start: %p, Bss end: %p0,exeinfo->address_info.bss_start,exeinfo->address_info.bss_end);

DATA STRUCTURES


   typedef struct _papi_address_map {
      char name[PAPI_HUGE_STR_LEN];
      caddr_t text_start;       /* Start address of program text segment */
      caddr_t text_end;         /* End address of program text segment */
      caddr_t data_start;       /* Start address of program data segment */
      caddr_t data_end;         /* End address of program data segment */
      caddr_t bss_start;        /* Start address of program bss segment */
      caddr_t bss_end;          /* End address of program bss segment */
   } PAPI_address_map_t;

typedef struct _papi_program_info { char fullname[PAPI_HUGE_STR_LEN]; /* path+name */ PAPI_address_map_t address_info; } PAPI_exe_info_t;

BUGS

Only the text_start and text_end fields are filled on every architecture.
