Virtual Method
GioPollableOutputStreamis_writable
since: 2.28
Description
Checks if stream
can be written.
Note that some stream types may not be able to implement this 100%
reliably, and it is possible that a call to g_output_stream_write()
after this returns TRUE
would still block. To guarantee
non-blocking behavior, you should always use
g_pollable_output_stream_write_nonblocking(), which will return a
G_IO_ERROR_WOULD_BLOCK
error rather than blocking.
