C API Example for sea-codec

This directory contains an example of how to use the C API of sea-codec from a C application.

Prerequisites

main.c: A simple C program that generates a sine wave, encodes it using sea-codec, and decodes it back.
CMakeLists.txt: A CMake build file demonstrating how to link against the sea-codec library.

Build the Rust library:

From the root of the repository:
```
cargo build --release
```
This will generate the static and dynamic libraries in target/release.

Build the C example:

cd examples/c_api
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

Run the example:

On Linux/macOS:
```
./c_example
```
On Windows:
```
.\Release\c_example.exe
```
(Note: If linking dynamically, ensure sea_codec.dll is in the same directory or in PATH).

The C header file is located at include/sea_codec.h. You should include this in your C/C++ projects.

To build a static library for a different platform (e.g., ARM Cortex-M3), use rustup to add the target and cargo to build:

rustup target add thumbv7m-none-eabi
cargo build --release --target thumbv7m-none-eabi --features c-api
