gFileReplaceReadwrite: gFileReplaceReadwrite

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

Returns an output stream for overwriting the file in readwrite mode, possibly creating a backup copy of the file first. If the file doesn't exist, it will be created.

Usage

gFileReplaceReadwrite(object, etag, make.backup, flags, cancellable = NULL, 
    .errwarn = TRUE)

Arguments

object	a GFile
etag	an optional entity tag for the current GFile, or NULL to ignore
make.backup	TRUE if a backup should be created
flags	a set of GFileCreateFlags
cancellable	optional GCancellable object, NULL to ignore
.errwarn	Whether to issue a warning on error or fail silently

Details

For details about the behaviour, see gFileReplace which does the same thing but returns an output stream only.

Note that in many non-local file cases read and write streams are not supported, so make sure you really need to do read and write streaming, rather than just opening for reading or writing. Since 2.22

Value

A list containing the following elements:

retval	[GFileIOStream] a GFileIOStream or NULL on error.
error	return location for a GError, or NULL
