Krzysku, najpierw wprowadzmy jedna ale za to porzadna zmiane i to w kodzie
zrodlowym programiku ktory ustawia PCI -> wolalbym tam sam nie grzebac...

Sprawa wyglada tak:

setpci.c:78: conflicting types for `pread'
/usr/include/unistd.h:320: previous declaration of `pread'
setpci.c:86: conflicting types for `pwrite'
/usr/include/unistd.h:322: previous declaration of `pwrite'
make: *** [setpci.o] Error 1

I dla przypomnienia interesujacy nas fragment kodu:

#ifdef __GLIBC__
#ifndef SYS_pread
#define SYS_pread __NR_pread
#endif
static int
pread(unsigned int fd, void *buf, size_t size, loff_t where)
{
  return syscall(SYS_pread, fd, buf, size, where);
}
#ifndef SYS_pwrite
#define SYS_pwrite __NR_pwrite
#endif
static int
pwrite(unsigned int fd, void *buf, size_t size, loff_t where)
{
  return syscall(SYS_pwrite, fd, buf, size, where);
}
#else
static _syscall4(int, pread, unsigned int, fd, void *, buf, size_t, size, loff_t, where);
static _syscall4(int, pwrite, unsigned int, fd, void *, buf, size_t, size, loff_t, where);
#endif
