Function
Giopollable_stream_read
Declaration
gssize
g_pollable_stream_read (
GInputStream* stream,
void* buffer,
gsize count,
gboolean blocking,
GCancellable* cancellable,
GError** error
)
Description
Tries to read from stream
, as with g_input_stream_read()
(if
blocking
is TRUE
) or g_pollable_input_stream_read_nonblocking()
(if blocking
is FALSE
). This can be used to more easily share
code between blocking and non-blocking implementations of a method.
If blocking
is FALSE
, then stream
must be a
GPollableInputStream
for which g_pollable_input_stream_can_poll()
returns TRUE
, or else the behavior is undefined. If blocking
is
TRUE
, then stream
does not need to be a GPollableInputStream
.
