Functions

• chdir
  Changes the working directory of the current process. See the Linux docs for details
• close
  Attempts to close the provided Fd. See the linux docs for details.
• copy_file_range
  Copies from one file-offset to another in-kernel
• dup2
  Duplicates old into new overwriting new if exists. See the Linux docs for details
• dup3
  Duplicates old into new overwriting new if exists, with flags See the Linux docs for details
• fcntl_get_file_status
  Get the file access mode and status flags See the Linux documentation for details
• fcntl_set_file_status
  Set file status flags, access mode and creation flags are valid, but ignored See the linux documentation for details
• get_dents
  Reads directory entities into the provided buffer and returns the number of bytes read See Linux docs for details
• get_uid
  Gets the userid of this process See the linux docs for details
• lseek
  Seek a fd See details in the linux docs here
• mkdir
  Create a directory named path See linux documentation for details
• mkdir_at
  Create a directory named path with dir_fd as the root directory See linux documentation for details
• mmap^⚠
  Map files or devices into memory. Almost impossible to make safe, and the linux documentation should be consulted for details.
• mount
  Mount a device. Attempt to mount a device from source to target specifying a FilesystemType and flags. Some filesystems allow providing additional data, which goes in data. See the linux docs for details.
• munmap^⚠
  Unmaps memory. Almost impossible to make safe, and the linux documentation should be consulted for details.
• open
  Attempts to open the fd at the path specified by a null terminated string, with the provided OpenFlags See the linux docs here
• open_at
  Attempts to open a file at the specified path from the opened directory (Fd) with the specified OpenFlags See the linux docs here
• open_at_mode
  Attempts to open a file at the specified path from the opened directory (Fd) with the specified OpenFlags and Mode See the linux docs here
• open_mode
  Attempts to open the fd at the path specified by a null terminated string, with the provided OpenFlags and Mode See the linux docs here
• open_raw^⚠
  Attempts to open the fd at the path described by the null terminated pointer supplied.
• pipe
  Creates a new set of pipes by utilizing the PIPE2 syscall See that documentation here
• pipe2
  Creates a new set of pipes by utilizing the PIPE2 syscall, with openflags See that documentation here
• read
  Attempts to read bytes up to the buffer’s len into the buffer from the provided Fd See linux docs for details
• rename
  Renames old_path to new_path overwriting any content at new_path
• rename_at
  Renames old_path to new_path with flags.
• rename_at2
  Renames old_path to new_path with flags.
• rename_flags
  Renames old_path to new_path with flags.
• rmdir
  Taking the liberty of using unlinkat for both implementations, effectively meaning that CWD is the base if the path isn’t absolute. Flags are either 0 or AT_REMOVEDIR “unlink, unlinkat - delete a name and possibly the file it refers to”docs
• setgid
  Sets the process’ group id to the provided gid See Linux documentation for details
• setpgid
  Sets process group id grp_pid to the process specified py set_pid See Linux documentation for detials
• setsid
  Creates a new session id if this process is not the current process group leader.
• setuid
  Sets the calling process’ uid to the provided uid See the Linux docs for details
• stat
  stat Gets file status at the path pointed to by path
• stat_fd
  fstat Gets file status at the file pointed to by Fd
• statat
  fstat Gets file status at the relative offset from dir_fd
• swapon
  Mount a swap. See the linux docs for details.
• uname
  Gets the UtsName struct See the linux docs for details
• unlink
  Taking the liberty of using unlinkat for both implementations, effectively meaning that CWD is the base if the path isn’t absolute “unlink, unlinkat - delete a name and possibly the file it refers to”docs
• unlink_at
  Taking the liberty of using unlinkat for both implementations, effectively meaning that CWD is the base if the path isn’t absolute. Flags are either 0 or AT_REMOVEDIR “unlink, unlinkat - delete a name and possibly the file it refers to”docs
• unlink_flags
  Unlink with a path from CWD and the provided flags. Flags are either 0 or AT_REMOVEDIR. “unlink, unlinkat - delete a name and possibly the file it refers to”docs
• unmount
  Unmount a device. Attempts to unmount the device at target. See the linux docs for details.
• unshare
  Unshare the properties specified by CloneFlags with other processes. See the Linux docs for details
• write
  Attempts to write bytes from the buffer to the corresponding fd. See linux syscall docs
