Declaration
void
g_input_stream_read_all_async (
GInputStream* stream,
void* buffer,
gsize count,
int io_priority,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer user_data
)
Description
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.
