Method
GioFilereplace_readwrite
Declaration
GFileIOStream*
g_file_replace_readwrite (
GFile* file,
const char* etag,
gboolean make_backup,
GFileCreateFlags flags,
GCancellable* cancellable,
GError** error
)
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.
For details about the behaviour, see g_file_replace()
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.
