Parameters

mode

A System.IO.FileMode value that specifies whether a file is created if one does not exist, and dtermines whether the contents of existing files are retained or overwritten.

access

A System.IO.FileAccess value that specifies the operations that can be performed on the file.

Returns

A Mono.Unix.UnixStream that provides access to UnixFileSystemInfo.FullName.

Exceptions

Type	Reason
ArgumentException	An attempt was made to open a descriptor with an illegal combination of Mono.Unix.Native.OpenFlags.O_RDONLY, Mono.Unix.Native.OpenFlags.O_WRONLY, and Mono.Unix.Native.OpenFlags.O_RDWR. [Mono.Unix.Native.Errno.EINVAL] -or- Mono.Unix.Native.OpenFlags.O_CREAT was specified in flags. Mono.Unix.Native.OpenFlags.O_CREAT requires a file mode for file creation; use UnixFileInfo.Open() instead.
InvalidOperationException	Mono.Unix.Native.OpenFlags.O_SHLOCK or Mono.Unix.Native.OpenFlags.O_EXLOCK is specified but the underlying file system does not support locking. [Mono.Unix.Native.Errno.EOPNOTSUPP] -or- UnixFileSystemInfo.FullName is a special file mounted through a file system that does not support access to it (e.g. NFS). [Mono.Unix.Native.Errno.EOPNOTSUPP] -or- An attempt was made to open a socket. [Mono.Unix.Native.Errno.EOPNOTSUPP]
UnauthorizedAccessException	Search permission is denied for a component of the path UnixFileSystemInfo.FullName. [Mono.Unix.Native.Errno.EACCESS] -or- The required permissions (for reading and/or writing) are denied for the given flags. [Mono.Unix.Native.Errno.EACCESS] -or- UnixFileSystemInfo.FullName does not exist, and UnixFileInfo.Directory does not permit writing. [Mono.Unix.Native.Errno.EACCESS] -or- UnixFileSystemInfo.FullName is a directory. [Mono.Unix.Native.Errno.EISDIR]
System.IO.DirectoryNotFoundException	A component of the path prefix of UnixFileSystemInfo.FullName is not a directory. [Mono.Unix.Native.Errno.ENOTDIR]
System.IO.FileNotFoundException	A component of UnixFileSystemInfo.FullName that must exist does not exist. [Mono.Unix.Native.Errno.ENOENT] -or- UnixFileSystemInfo.FullName does not exist and Mono.Unix.Native.OpenFlags.O_CREAT is not set. [Mono.Unix.Native.Errno.ENOENT]
System.IO.IOException	UnixFileSystemInfo.FullName resides on a read-only file system. [Mono.Unix.Native.Errno.EROFS] -or- UnixFileSystemInfo.FullName is a character device or block device, and the device associated with this file does not exist. [Mono.Unix.Native.Errno.ENXIO] -or- UnixFileSystemInfo.FullName is a fifo, no process has it open for reading, and the arguments specify it is to be opened for writing. [Mono.Unix.Native.Errno.ENXIO] -or- The directory UnixFileInfo.Directory cannot be extended because there is no space left on the file system containing the directory. [Mono.Unix.Native.Errno.ENOSPC] -or- There are no free inodes on the file system on which the file is being created. [Mono.Unix.Native.Errno.ENOSPC] -or- An I/O error occurred while making the directory entry or allocating the inode. [Mono.Unix.Native.Errno.EIO]
System.IO.PathTooLongException	UnixFileSystemInfo.FullName was too long. [Mono.Unix.Native.Errno.ENAMETOOLONG]
Mono.Unix.UnixIOException	Too many symbolic links were encountered in translating UnixFileSystemInfo.FullName. [Mono.Unix.Native.Errno.ELOOP] -or- The process has already reached its limit for open file descriptors. [Mono.Unix.Native.Errno.EMFILE] -or- The system file table is full. [Mono.Unix.Native.Errno.ENFILE] -or- Mono.Unix.Native.OpenFlags.O_NOFOLLOW was specified and the target is a symbolic link. [Mono.Unix.Native.Errno.EMLINK] -or- Mono.Unix.Native.OpenFlags.O_NONBLOCK and one of Mono.Unix.Native.OpenFlags.O_SHLOCK or Mono.Unix.Native.OpenFlags.O_EXLOCK is specified and the file is locked. [Mono.Unix.Native.Errno.EWOULDBLOCK] -or- The user's quota of inodes on the file system containing UnixFileInfo.Directory has been exhausted. [Mono.Unix.Native.Errno.EDQUOT] -or- UnixFileInfo.Directory cannot be extended because the user's quota of disk blocks on the file system containing this directory has been exhausted. [Mono.Unix.Native.Errno.EDQUOT] -or- UnixFileSystemInfo.FullName is a pure procedure (shared text) file that is being executed and Mono.Unix.Native.Syscall.open requests write access. [Mono.Unix.Native.Errno.ETXTBSY] -or- Mono.Unix.Native.OpenFlags.O_CREAT and Mono.Unix.Native.OpenFlags.O_EXCL were specified and UnixFileSystemInfo.FullName exists. [Mono.Unix.Native.Errno.EEXIST]

Remarks

This is equivalent to UnixFileInfo.Open(Mono.Unix.Native.OpenFlags) (Mono.Unix.Native.NativeConvert.ToOpenFlags(System.IO.FileMode, System.IO.FileAccess) (mode, access)).
