NAME
PAPI_get_executable_info - get the executable's address space infoSYNOPSIS
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: %s,exeinfo->fullname); printf("Program: %s,exeinfo->address_info.name); printf("Text start: %p, Text end: %p,exeinfo->address_info.text_start,exeinfo->address_info.text_end); printf("Data start: %p, Data end: %p,exeinfo->address_info.data_start,exeinfo->address_info.data_end); printf("Bss start: %p, Bss end: %p,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.SEE ALSO
