## Member Enumeration Documentation

enum Gio::Error::Code

Error codes returned by GIO functions.

Note that this domain may be extended in future GLib releases. In general, new error codes either only apply to new APIs, or else replace IO_ERROR_FAILED in cases that were not explicitly distinguished before. You should therefore avoid writing code like

[C example ellipted] but should instead treat all unrecognized error codes the same as IO_ERROR_FAILED.

Enumerator
FAILED | Generic error condition for when an operation fails and no more specific IOErrorEnum value is defined.
NOT_FOUND | File not found.
EXISTS | File already exists.
IS_DIRECTORY | File is a directory.
NOT_DIRECTORY | File is not a directory.
NOT_EMPTY | File is a directory that isn't empty.
NOT_REGULAR_FILE | File is not a regular file.
NOT_SYMBOLIC_LINK | File is not a symbolic link.
NOT_MOUNTABLE_FILE | File cannot be mounted.
FILENAME_TOO_LONG | Filename is too many characters.
INVALID_FILENAME | Filename is invalid or contains invalid characters.
TOO_MANY_LINKS | File contains too many symbolic links.
NO_SPACE | No space left on drive.
INVALID_ARGUMENT | Invalid argument.
PERMISSION_DENIED | Permission denied.
NOT_SUPPORTED | Operation (or one of its parameters) not supported.
NOT_MOUNTED | File isn't mounted.
ALREADY_MOUNTED | File is already mounted.
CLOSED | File was closed.
CANCELLED | Operation was cancelled. See Cancellable.
PENDING | Operations are still pending.
READ_ONLY | File is read only.
CANT_CREATE_BACKUP | Backup couldn't be created.
WRONG_ETAG | File's Entity Tag was incorrect.
TIMED_OUT | Operation timed out.
WOULD_RECURSE | Operation would be recursive.
BUSY | File is busy.
WOULD_BLOCK | Operation would block.
HOST_NOT_FOUND | Host couldn't be found (remote operations).
HOST_WAS_NOT_FOUND |
WOULD_MERGE | Operation would merge files.
FAILED_HANDLED | Operation failed and a helper program has already interacted with the user. Do not display any error dialog.
TOO_MANY_OPEN_FILES | The current process has too many files open and can't open any more. Duplicate descriptors do count toward this limit. Since glibmm 2.20:
NOT_INITIALIZED | The object has not been initialized. Since glibmm 2.22:
ADDRESS_IN_USE | The requested address is already in use. Since glibmm 2.22:
PARTIAL_INPUT | Need more input to finish operation. Since glibmm 2.24:
INVALID_DATA | The input data was invalid. Since glibmm 2.24:
DBUS_ERROR | A remote object generated an error that doesn't correspond to a locally registered Error error domain. Use g_dbus_error_get_remote_error() to extract the D-Bus error name and g_dbus_error_strip_remote_error() to fix up the message so it matches what was received on the wire. Since glibmm 2.26:
HOST_UNREACHABLE | Host unreachable. Since glibmm 2.26:
NETWORK_UNREACHABLE | Network unreachable. Since glibmm 2.26:
CONNECTION_REFUSED | Connection refused. Since glibmm 2.26:
PROXY_FAILED | Connection to proxy server failed. Since glibmm 2.26:
PROXY_AUTH_FAILED | Proxy authentication failed. Since glibmm 2.26:
PROXY_NEED_AUTH | Proxy server needs authentication. Since glibmm 2.26:
PROXY_NOT_ALLOWED | Proxy connection is not allowed by ruleset. Since glibmm 2.26:
BROKEN_PIPE | Broken pipe. Since glibmm 2.36:
CONNECTION_CLOSED | Connection closed by peer. Note that this is the same code as IO_ERROR_BROKEN_PIPE; before 2.44 some "connection closed" errors returned IO_ERROR_BROKEN_PIPE, but others returned IO_ERROR_FAILED. Now they should all return the same value, which has this more logical name. Since glibmm 2.44:
NOT_CONNECTED | Transport endpoint is not connected. Since glibmm 2.44:
MESSAGE_TOO_LARGE | Message too large. Since glibmm 2.48:
