Description
|
|
Packit |
ae235b |
Buffered output stream implements GFilterOutputStream and provides
|
|
Packit |
ae235b |
for buffered writes.
|
|
Packit |
ae235b |
By default, GBufferedOutputStream's buffer size is set at 4 kilobytes.
|
|
Packit |
ae235b |
To create a buffered output stream, use g_buffered_output_stream_new(),
|
|
Packit |
ae235b |
or g_buffered_output_stream_new_sized() to specify the buffer's size
|
|
Packit |
ae235b |
at construction.
|
|
Packit |
ae235b |
To get the size of a buffer within a buffered input stream, use
|
|
Packit |
ae235b |
g_buffered_output_stream_get_buffer_size(). To change the size of a
|
|
Packit |
ae235b |
buffered output stream's buffer, use
|
|
Packit |
ae235b |
g_buffered_output_stream_set_buffer_size(). Note that the buffer's
|
|
Packit |
ae235b |
size cannot be reduced below the size of the data within the buffer.
