FdRightsFlag

The right to invoke fd_advise.

The right to invoke fd_allocate.

The right to invoke fd_datasync. If path_open is set, includes the right to invoke path_open with fdflags::dsync.

The right to invoke fd_fdstat_set_flags.

The right to invoke fd_filestat_get.

The right to invoke fd_filestat_set_size.

The right to invoke fd_filestat_set_times.

The right to invoke fd_read and sock_recv. If rights::fd_seek is set, includes the right to invoke fd_pread.

The right to invoke fd_readdir.

The right to invoke fd_seek. This flag implies rights::fd_tell.

The right to invoke fd_sync. If path_open is set, includes the right to invoke path_open with fdflags::rsync and fdflags::dsync.

The right to invoke fd_seek in such a way that the file offset remains unaltered (i.e., whence::cur with offset zero), or to invoke fd_tell.

The right to invoke fd_write and sock_send. If rights::fd_seek is set, includes the right to invoke fd_pwrite.

The right to invoke path_create_directory.

If path_open is set, the right to invoke path_open with oflags::creat.

The right to invoke path_filestat_get.

The right to change a file's size. If path_open is set, includes the right to invoke path_open with oflags::trunc. Note: there is no function named path_filestat_set_size. This follows POSIX design, which only has ftruncate and does not provide ftruncateat. While such function would be desirable from the API design perspective, there are virtually no use cases for it since no code written for POSIX systems would use it. Moreover, implementing it would require multiple syscalls, leading to inferior performance.

The right to invoke path_filestat_set_times.

The right to invoke path_link with the file descriptor as the source directory.

The right to invoke path_link with the file descriptor as the target directory.

The right to invoke path_open.

The right to invoke path_readlink.

The right to invoke path_remove_directory.

The right to invoke path_rename with the file descriptor as the source directory.

The right to invoke path_rename with the file descriptor as the target directory.

The right to invoke path_symlink.

The right to invoke path_unlink_file.

If rights::fd_read is set, includes the right to invoke poll_oneoff to subscribe to eventtype::fd_read. If rights::fd_write is set, includes the right to invoke poll_oneoff to subscribe to eventtype::fd_write.

The right to invoke sock_accept.

The right to invoke sock_shutdown.
