PAPIF_get_exe_info(C_STRING fullname, C_STRING name,  
           C_LONG_LONG  text_start, 

        C_LONG_LONG C_LONG_LONG data_start,  
           C_LONG_LONG  data_end,

        C_LONG_LONG C_LONG_LONG bss_end, 

        C_INT  

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

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

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.

PAPI_EINVAL
	One or more of the arguments is invalid.
