# HTTP `PUT` example
|
||||
|
||||
This example shows a minimal setup for an application using `libweb` that only
|
||||
accepts `PUT` requests. When executed, it starts a HTTP/1.1 server on a random
|
||||
port that shall be printed to standard output. When a `PUT` request is received,
|
||||
`libweb` shall store the body into a file in the `/tmp` directory, and print the
|
||||
path of the temporary file to the standard output.
|
||||
|
||||
## How to build
|
||||
|
||||
If using `make(1)`, just run `make` from this directory.
|
||||
|
||||
If using CMake, examples are built by default when configuring the project
|
||||
from [the top-level `CMakeLists.txt`](../../CMakeLists.txt).
|
||||
|
||||
## How to run
|
||||
|
||||
Run the executable without any command line arguments.
