Hi everyone,
I want (again) to call a Fortran function from C++. Now I know how to do this when I have the source or object file, but I think that it should be possible to do this directly with the .so or .dll ?
Also, does anyone know a program which lists functions in a .so file, like one can read the exported functions in a .dll file? http://www.nirsoft.net/utils/dll_export_viewer.html
Thanks a lot in advance!
I don't know about 'nix, but from windows you use the API calls 'LoadLibrary' and 'GetProcAddress', eg:
Code:typedef int ( * foo_function )( double ); HMODULE library = LoadLibrary( "foo.dll" ); if( library ) { foo_function function = foo_function( GetProcAddress( library, "baz" ) ); if( function ) { int result = function( 2.0 ); } FreeLibrary( library ); }
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
Static objects you *usually* get the imported symbols loaded in during compile time.
