独立于平台的字体定位方式
我正在开发一个 C 语言的多平台应用程序，我需要从磁盘加载字体并使用 FreeType 渲染消息。但是，我目前使用完整路径来定位字体，并且向用户询问字体的完整路径有点尴尬，因为它们通常深埋在系统文件夹中。
有没有一种简单的、独立于平台的方法来定位字体？例如，我可以期望用户能够提供类似“Sans”的内容，并有一个库或其他东西为我找到该字体的完整路径。我知道 fontconfig 的存在，但我发现很难浏览它的文档。
澄清：这是一个 CLI 驱动的应用程序，通过配置文件进行配置。
I'm working on a multi-platform application in C where I need to load fonts from disk and render messages with FreeType. However, I currently use full paths for locating fonts, and it's somewhat awkward to ask users for the full path of fonts since they are generally buried deep into system folders.
Is there a simple, platform-idependent way of just locating fonts? E.g. I can expect users to be able to provide something like "Sans" and have a library or something locate the full path of this font for me. I'm aware of the existence of fontconfig, but I found it quite hard to go through the documentation for it.
Clarification: This is a CLI driven application, which is configured through a config file.

据我所知，
fontconfig就是这样。继续查看文档，并找到一些教程。 这个 pdf 虽然有点旧，但很好地概述了 fontconfig 如何进行完成其非常有用的工作。As far as I am aware,
fontconfigis the way. Keep at the docs, and find some tutorials. This pdf, while a little old, gives a very nice overview of how fontconfig does its amazingly useful job.您能够以独立于平台的方式获取该信息的唯一方法是拥有一个跨平台包来隐藏差异。它将为您提供一个平台中立的界面，并且本身会处理每个平台的复杂性。
The only way you could get that information in a platform-independent way is to have a cross-platform package that conceals the differences from you. It would provide you with a platform-neutral interface and would itself deal with the complexities of each platform.
