I would suggest you to use fseek-ftell functions. FILE *stream = fopen("example.txt", "r"); if(!stream) { puts("I/O error.\n"); return; } fseek(stream, 0, SEEK_END); long size = ftell(stream); fseek(stream, 0, SEEK_SET); while(1) { if(ftell(stream) == size) { brea...

fseek($f, 0); Next, we will set the response headers to export the CSV file. header('Content-Type: text/csv'); header('Content-Disposition: attachment; filename="' . $filename . '";'); Now, output all remaining data on a file pointer. ...
(secure-execution-mode not enabled), on GNU/Linux systems at least, you can convince the dynamic linker to inject arbitrary code into the executable with the $LD_PRELOAD mechanism, or tell it to use modified versions of the shared libraries it uses that have been hijacked...
