# libtuberia
libtuberia: a library to implement a pipeline
A pipeline would be:
*[Source] -> [queue_1] -> [Stage_1] -> [Queue_2] -> [Stage_2] -> [...] -> [Sink]*
Each source, stage, and sink runs in a thread, reads from its imput queue and
write to the output queue
You can ommit the source and sink, and inject or retrive elements from the
pipeline
## Building, Compiling, Installing
If you don't have a ./configure file, run:
- `autoreconf -fi`
When you have the ./configure file, run:
- `./configure`
- `make`
- `make install`
You can see some configuration options with:
- `./configure --help`
## Quick Guide
See the `example/decode_resize_encode.c` and the function `do_tuberia()`
Create a source with `tube_source_alloc()`.
If you set fetch to something, there will be a thread running fetch to inject
elements into the pipeline.
If you set fetch to NULL, you have to inject the elements with `tube_inject()`.
Create as many stages as you need with `tube_stage_alloc()`, and append them
to the source with `tube_stage_append()`.
Build the pipeline with `tube_alloc()`. If you set sink to something,
there will be a thread running sink to get the elements from the pipeline.
If you set sink to NULL, you have to retrieve the elements with
`tube_retrieve()`.
The `tube_alloc()` function copies the source and all the appended stages,
so you can free the source and stages with `tube_source_and_stages_free()`.
Or, you can reutilize the same `tube_source` to build more pipelines.
Start the pipeline with `tube_start()`.
Free the pipeline with `tube_free()`.
### Quick example
```C
