• fstat
  Get metadata about a file
• fstatvfs

• fsync
  Sync a file descriptor to its underlying medium
• ftruncate

• funmap^⚠
  Unmap whole (or partial) continous memory-mapped files
• futex^⚠
  Fast userspace mutex
• futimens
• getegid
  Get the effective group ID
• getens
  Get the effective namespace
• geteuid
  Get the effective user ID
• getgid
  Get the current group ID
• getns
  Get the current namespace
• getpgid
  Get the process group ID
• getpid
  Get the current process ID
• getppid
  Get the parent process ID
• getuid
  Get the current user ID
• iopl^⚠
  Set the I/O privilege level
• kill
  Send a signal sig to the process identified by pid
• link^⚠
  Create a link to a file
• lseek
  Seek to offset bytes in a file descriptor
• mkns
  Make a new scheme namespace
• mprotect^⚠
  Change mapping flags
• nanosleep
  Sleep for the time specified in req
• open
  Open a file
• physalloc^⚠
  Allocate frames, linearly in physical memory.
• physalloc2^⚠
  Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain PARTIAL_ALLOC, this will result in physalloc3 with min = 1.
• physalloc3^⚠
  Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain PARTIAL_ALLOC, the min parameter specifies the number of frames that have to be allocated for this operation to succeed. The return value is the offset of the first frame, and min is overwritten with the number of frames actually allocated.
• physfree^⚠
  Free physically allocated pages

  Map physical memory to virtual memory
• read
  Read from a file descriptor into a buffer
• rmdir
  Remove a directory
• sched_yield
  Yield the process’s time slice to the kernel
• setpgid
  Set the process group ID
• setregid
  Set the current process group IDs
• setrens
  Make a new scheme namespace
• setreuid
  Set the current process user IDs
• sigaction
  Set up a signal handler
• sigprocmask
  Get and/or set signal masks
• sigreturn
• umask
  Set the file mode creation mask
• unlink
  Remove a file
• virttophys^⚠
  Convert a virtual address to a physical one
• waitpid
  Check if a child process has exited or received a signal
• write
  Write a buffer to a file descriptor
