C++ (Cpp) INLINE_SYSCALL_CALL Examples

Example #1

File: semtimedop.c Project: riscv/riscv-glibc

int
semtimedop (int semid, struct sembuf *sops, size_t nsops,
	    const struct timespec *timeout)
{
#ifdef __ASSUME_DIRECT_SYSVIPC_SYSCALLS
  return INLINE_SYSCALL_CALL (semtimedop, semid, sops, nsops, timeout);
#else
  return INLINE_SYSCALL_CALL (ipc, IPCOP_semtimedop, semid, nsops, 0, sops,
			      timeout);
#endif
}

Example #2

ssize_t
__readahead (int fd, off64_t offset, size_t count)
{
  return INLINE_SYSCALL_CALL (readahead, fd,
			      __ALIGNMENT_ARG SYSCALL_LL64 (offset),
			      count);
}

Example #3

File: open64.c Project: riscv/riscv-glibc

int

{
  int mode = 0;

  if (__OPEN_NEEDS_MODE (oflag))

      va_list arg;

      va_end (arg);
    }

  return INLINE_SYSCALL_CALL (openat, AT_FDCWD, file, oflag | EXTRA_OPEN_FLAGS,
			      mode);
}

Example #4

int

       unsigned int mask, struct statx *buf)
