Expand description

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 Failed in cases that were not explicitly distinguished before. You should therefore avoid writing code like

⚠️ The following code is in C ⚠️

if (g_error_matches (error, G_IO_ERROR, G_IO_ERROR_FAILED))
  {
    // Assume that this is EPRINTERONFIRE
    ...
  }

but should instead treat all unrecognized error codes the same as Failed.

See also #GPollableReturn for a cheaper way of returning WouldBlock to callers without allocating a #GError.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Failed

Generic error condition for when an operation fails and no more specific #GIOErrorEnum value is defined.

§

NotFound

File not found.

§

Exists

File already exists.

§

IsDirectory

File is a directory.

§

NotDirectory

File is not a directory.

§

NotEmpty

File is a directory that isn’t empty.

§

NotRegularFile

File is not a regular file.

File is not a symbolic link.

§

NotMountableFile

File cannot be mounted.

§

FilenameTooLong

Filename is too many characters.

§

InvalidFilename

Filename is invalid or contains invalid characters.

File contains too many symbolic links.

§

NoSpace

No space left on drive.

§

InvalidArgument

Invalid argument.

§

PermissionDenied

Permission denied.

§

NotSupported

Operation (or one of its parameters) not supported

§

NotMounted

File isn’t mounted.

§

§

DbusError

A remote object generated an error that doesn’t correspond to a locally registered #GError 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 2.26.

§

DestinationUnset

Available on crate feature v2_80 only.

Destination address unset. Since 2.80
