rose-lib-ffi

Roselib FFI

Foreign function interface for the roselib library.

This library wraps roselib and exposes some of its functionality using Rust FFI. The functionality is exposed as a C-API with a generated header file and corresponding static/dynamic libraries.

Please refer to the README in roselib for more information about the purpose of this library.

NOTE The current focus on this library is for wrapping only read functionality.

Usage

Please refer to the test file(s) for general usage.

To use as part of a C/C++ program, first build the library with cargo build. This will create the libraries in the target/ directory and the header file in include/. Include/link these in your project as needed.

Example

#include <string.h>
#include "roselib.h"

DataTable* stb = data_table_new();

bool res = data_table_read(stb, "list_zone.stb");
assert(res == true);

int rows = data_table_rows(stb);
assert(rows == 121);

int cols = data_table_cols(stb);
assert(cols == 38);

FfiString* data = ffi_string_new();

res = data_table_get_header(stb, 2, data);
assert(res == true);
assert(strcmp(res.chars, "ZON") == 0);

res = data_table_get_data(stb, 2, 2, data);
assert(res == true);
assert(strcmp(res.chars, ""3DDATA\\Maps\\Junon\\JPT01\\JPT01.zon"") == 0);

ffi_string_free(data);
data_table_free(stb);
