Declaration [src]
void
g_input_stream_read_all_async (
GInputStream* stream,
void* buffer,
gsize count,
int io_priority,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer user_data
)
Description [src]
Request an asynchronous read of count bytes from the stream into the
buffer starting at buffer.
This is the asynchronous equivalent of g_input_stream_read_all().
Call g_input_stream_read_all_finish() to collect the result.
Any outstanding I/O request with higher priority (lower numerical
value) will be executed before an outstanding request with lower
priority. Default priority is G_PRIORITY_DEFAULT.
Available since: 2.44
This method completes asynchronously. Use g_input_stream_read_all_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
Parameters
buffer-
Type: An array of
guint8a buffer to read data into (which should be at least count bytes long).
The argument will be set by the function. The length of the array is specified in the countargument.The returned data is owned by the instance. count-
Type:
gsizeThe number of bytes that will be read from the stream.
io_priority-
Type:
intThe I/O priority of the request.
cancellable-
Type:
GCancellableOptional
GCancellableobject,NULLto ignore.The argument can be NULL.The data is owned by the caller of the method. callback-
Type:
GAsyncReadyCallbackA
GAsyncReadyCallbackto call when the request is satisfied.The argument can be NULL. user_data-
Type:
gpointerThe data to pass to callback function.
The argument can be NULL.The data is owned by the caller of the method.
