Include dependency graph for vfs.h:

This graph shows which files directly or indirectly include this file:

Macros
#define	VFS_ROOT_ENTRY_NAME "__root__"
	The name of the root entry.

#define	VFS_DEVICE_NAME_NONE "__no_device__"
	The name used to indicate no device.

#define	BUFFER_READ(buffer, count, offset, src, size)
	Helper macros for implementing file operations dealing with simple buffers.

#define	BUFFER_WRITE(buffer, count, offset, src, size)
	Helper macro for implementing file operations dealing with simple buffer writes.

Functions
file_t *	vfs_open (const pathname_t pathname, process_t process)
	Open a file.

uint64_t	vfs_open2 (const pathname_t pathname, file_t files[2], process_t *process)
	Open one file, returning two file handles.

file_t *	vfs_openat (const path_t from, const pathname_t pathname, process_t *process)
	Open a file relative to another path.

uint64_t	vfs_read (file_t file, void buffer, uint64_t count)
	Read from a file.

uint64_t	vfs_write (file_t file, const void buffer, uint64_t count)
	Write to a file.

uint64_t	vfs_seek (file_t *file, int64_t offset, seek_origin_t origin)
	Seek in a file.

uint64_t	vfs_ioctl (file_t file, uint64_t request, void argp, uint64_t size)
	Perform an ioctl operation on a file.

void *	vfs_mmap (file_t file, void address, uint64_t length, pml_flags_t flags)
	Memory map a file.

uint64_t	vfs_poll (poll_file_t *files, uint64_t amount, clock_t timeout)
	Poll multiple files.

uint64_t	vfs_getdents (file_t file, dirent_t buffer, uint64_t count)
	Get directory entries from a directory file.

uint64_t	vfs_stat (const pathname_t pathname, stat_t buffer, process_t *process)
	Get file information.

uint64_t	vfs_link (const pathname_t oldPathname, const pathname_t newPathname, process_t *process)
	Make the same file appear twice in the filesystem.

uint64_t	vfs_remove (const pathname_t pathname, process_t process)
	Remove a file or directory.

uint64_t	vfs_id_get (void)
	Generates a new unique ID, to be used for any VFS object.
