I'm facing an issue with ffi-napi when working with callback functions that return strings of unknown lengths from a C++ library. The problem is that I need to set csStringPointer.size to a specific value before calling the C++ function, but I don't know the exact length of the returne...
在NodeJS中使用ffi (-napi)是一种通过调用外部动态链接库(DLL)或共享对象(SO)文件的方式来实现与C/C++代码的交互的方法。ffi是Foreign Function Interface的缩写,它允许NodeJS应用程序直接调用本地的C/C++函数,从而扩展了NodeJS的功能。 ffi-napi是NodeJS的一个模块,它提供了一种跨平台的方式来使用ffi。它使用了...
