Hello list,
I wonder why lseek(SEEK_CUR) on open(O_RDWR) fails with errno=22, the
code works on Linux:
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <fcntl.h>
int main(int argc, char** argv){
Where's #include <unistd.h>? It fails because you are missing the
prototype for lseeks, which means that the C compiler is trying to call
it with 'int offset' instead of 'off_t offset'. Compile with -Wall.
Whats wrong with cygwin?
Rather, fix the bugs in your code, and let the compiler help you.
Got it, but why enforcing the use of off_t here?
I'm not going to use 64bit offsets.
