namespace constants

const COPYFILE_EXCL: number
Constant for fs.copyFile. Flag indicating the destination file should not be overwritten if it already exists.
const COPYFILE_FICLONE: number
Constant for fs.copyFile. copy operation will attempt to create a copy-on-write reflink. If the underlying platform does not support copy-on-write, then a fallback copy mechanism is used.
const COPYFILE_FICLONE_FORCE: number
Constant for fs.copyFile. Copy operation will attempt to create a copy-on-write reflink. If the underlying platform does not support copy-on-write, then the operation will fail with an error.
const F_OK: number
Constant for fs.access(). File is visible to the calling process.
const O_APPEND: number
Constant for fs.open(). Flag indicating that data will be appended to the end of the file.
const O_CREAT: number
Constant for fs.open(). Flag indicating to create the file if it does not already exist.
const O_DIRECT: number
Constant for fs.open(). When set, an attempt will be made to minimize caching effects of file I/O.
const O_DIRECTORY: number
Constant for fs.open(). Flag indicating that the open should fail if the path is not a directory.
const O_DSYNC: number
Constant for fs.open(). Flag indicating that the file is opened for synchronous I/O with write operations waiting for data integrity.
const O_EXCL: number
Constant for fs.open(). Flag indicating that opening a file should fail if the O_CREAT flag is set and the file already exists.
const O_NOATIME: number
constant for fs.open(). Flag indicating reading accesses to the file system will no longer result in an update to the atime information associated with the file. This flag is available on Linux operating systems only.
const O_NOCTTY: number
Constant for fs.open(). Flag indicating that if path identifies a terminal device, opening the path shall not cause that terminal to become the controlling terminal for the process (if the process does not already have one).
const O_NOFOLLOW: number
Constant for fs.open(). Flag indicating that the open should fail if the path is a symbolic link.
const O_NONBLOCK: number
Constant for fs.open(). Flag indicating to open the file in nonblocking mode when possible.
const O_RDONLY: number
Constant for fs.open(). Flag indicating to open a file for read-only access.
const O_RDWR: number
Constant for fs.open(). Flag indicating to open a file for read-write access.
const O_SYMLINK: number
Constant for fs.open(). Flag indicating to open the symbolic link itself rather than the resource it is pointing to.
const O_SYNC: number
Constant for fs.open(). Flag indicating that the file is opened for synchronous I/O.
const O_TRUNC: number
Constant for fs.open(). Flag indicating that if the file exists and is a regular file, and the file is opened successfully for write access, its length shall be truncated to zero.
const O_WRONLY: number
Constant for fs.open(). Flag indicating to open a file for write-only access.
const R_OK: number
Constant for fs.access(). File can be read by the calling process.
const S_IFBLK: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a block-oriented device file.
const S_IFCHR: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a character-oriented device file.
const S_IFDIR: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a directory.
const S_IFIFO: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a FIFO/pipe.
const S_IFLNK: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a symbolic link.
const S_IFMT: number
Constant for fs.Stats mode property for determining a file's type. Bit mask used to extract the file type code.
const S_IFREG: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a regular file.
const S_IFSOCK: number
Constant for fs.Stats mode property for determining a file's type. File type constant for a socket.
const S_IRGRP: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable by group.
const S_IROTH: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable by others.
const S_IRUSR: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable by owner.
const S_IRWXG: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable, writable and executable by group.
const S_IRWXO: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable, writable and executable by others.
const S_IRWXU: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating readable, writable and executable by owner.
const S_IWGRP: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating writable by group.
const S_IWOTH: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating writable by others.
const S_IWUSR: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating writable by owner.
const S_IXGRP: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating executable by group.
const S_IXOTH: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating executable by others.
const S_IXUSR: number
Constant for fs.Stats mode property for determining access permissions for a file. File mode indicating executable by owner.
const UV_FS_O_FILEMAP: number
When set, a memory file mapping is used to access the file. This flag is available on Windows operating systems only. On other operating systems, this flag is ignored.
const W_OK: number
Constant for fs.access(). File can be written by the calling process.
const X_OK: number
Constant for fs.access(). File can be executed by the calling process.
