In C or C++, the following can be used to return a file size: const unsigned long long at_beg = (unsigned long long) ftell(filePtr); fseek(filePtr, 0, SEEK_END); const unsigned long long at_end = ...

Is there a way to do what ftell() does (return the current position in the file) on a raw file descriptor instead of a FILE*? I think there ought to be, since you can seek on a raw file descriptor ...

The following code outputs "Illegal seek": #include <stdio.h> #include <errno.h> #include <string.h> int main() { errno = 0; getchar(); getchar(); getchar(); ftell( stdin ...

Very simply put, I have the following code snippet: FILE* test = fopen("C:\\core.u", "w"); printf("Filepointer at: %d\n", ftell(test)); fwrite(data, size, 1, test); printf("Written: %d bytes.\n", ...

FILE *out=fopen64("text.txt","w+"); unsigned int write; char *outbuf=new char[write]; //fill outbuf printf("%i\n",ftello64(out)); fwrite(outbuf,sizeof(char),write,out); printf("%i\n",write); printf...
