§format: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct) -> i32>@brief Format the file system on the given mount point
@param[in] mountp file system to format
@return 0 on success @return <0 on error
mount: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct) -> i32>@brief Perform any extra processing needed after mounting a file system
If this call returns an error, the whole vfs_mount call will signal a failure.
All fields of @p mountp will be initialized by vfs_mount beforehand, @c private_data will be initialized to NULL.
@param[in] mountp file system mount being mounted
@return 0 on success @return <0 on error
umount: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct) -> i32>@brief Perform the necessary clean up for unmounting a file system
@param[in] mountp file system mount being unmounted
@return 0 on success @return <0 on error
rename: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8, _: *const u8) -> i32>@brief Rename a file
The file @p from_path will be renamed to @p to_path
@note it is not possible to rename files across different file system
@param[in] mountp file system mount to operate on @param[in] from_path absolute path to existing file @param[in] to_path absolute path to destination
@return 0 on success @return <0 on error
unlink: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8) -> i32>@brief Unlink (delete) a file from the file system
@param[in] mountp file system mount to operate on @param[in] name name of the file to delete
@return 0 on success @return <0 on error
mkdir: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8, _: u32) -> i32>@brief Create a directory on the file system
@param[in] mountp file system mount to operate on @param[in] name name of the directory to create @param[in] mode file creation mode bits
@return 0 on success @return <0 on error
rmdir: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8) -> i32>@brief Remove a directory from the file system
Only empty directories may be removed.
@param[in] mountp file system mount to operate on @param[in] name name of the directory to remove
@return 0 on success @return <0 on error
stat: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8, _: *mut stat) -> i32>@brief Get file status
@param[in] mountp file system mount to operate on @param[in] path path to file being queried @param[out] buf pointer to stat struct to fill
@return 0 on success @return <0 on error
statvfs: Option<unsafe extern "C" fn(_: *mut vfs_mount_struct, _: *const u8, _: *mut statvfs) -> i32>@brief Get file system status
@p path is only passed for consistency against the POSIX statvfs function. @c vfs_statvfs calls this function only when it has determined that @p path belongs to this file system. @p path is a file system relative path and does not necessarily name an existing file.
@param[in] mountp file system mount to operate on @param[in] path path to a file on the file system being queried @param[out] buf pointer to statvfs struct to fill
@return 0 on success @return <0 on error
