{- |
Registers /@uriFunc@/ and /@parseNameFunc@/ as the 'GI.Gio.Interfaces.File.File' URI and parse name
lookup functions for URIs with a scheme matching /@scheme@/.
Note that /@scheme@/ is registered only within the running application, as
opposed to desktop-wide as it happens with GVfs backends.

When a 'GI.Gio.Interfaces.File.File' is requested with an URI containing /@scheme@/ (e.g. through
'GI.Gio.Functions.fileNewForUri'), /@uriFunc@/ will be called to allow a custom
constructor. The implementation of /@uriFunc@/ should not be blocking, and
must not call 'GI.Gio.Objects.Vfs.vfsRegisterUriScheme' or 'GI.Gio.Objects.Vfs.vfsUnregisterUriScheme'.

When 'GI.Gio.Functions.fileParseName' is called with a parse name obtained from such file,
/@parseNameFunc@/ will be called to allow the 'GI.Gio.Interfaces.File.File' to be created again. In
that case, it\'s responsibility of /@parseNameFunc@/ to make sure the parse
name matches what the custom 'GI.Gio.Interfaces.File.File' implementation returned when
'GI.Gio.Interfaces.File.fileGetParseName' was previously called. The implementation of
/@parseNameFunc@/ should not be blocking, and must not call
'GI.Gio.Objects.Vfs.vfsRegisterUriScheme' or 'GI.Gio.Objects.Vfs.vfsUnregisterUriScheme'.

It\'s an error to call this function twice with the same scheme. To unregister
a custom URI scheme, use 'GI.Gio.Objects.Vfs.vfsUnregisterUriScheme'.
