Method
GioFilereplace_contents_async
Declaration [src]
void
g_file_replace_contents_async (
GFile* file,
const char* contents,
gsize length,
const char* etag,
gboolean make_backup,
GFileCreateFlags flags,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer user_data
)
Description [src]
Starts an asynchronous replacement of file with the given
contents of length bytes. etag will replace the document’s
current entity tag.
When this operation has completed, callback will be called with
user_user data, and the operation can be finalized with g_file_replace_contents_finish().
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If make_backup is TRUE, this function will attempt to
make a backup of file.
Note that no copy of contents will be made, so it must stay valid
until callback is called. See g_file_replace_contents_bytes_async()
for a GBytes version that will automatically hold a reference to the
contents (without copying) for the duration of the call.
This method completes asynchronously. Use g_file_replace_contents_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
