cImport

Zig's @cImport builtin is unique in that it takes in an expression, which can only take in @cInclude, @cDefine, and @cUndef. This works similarly to translate-c, translating C code to Zig under the hood.

@cInclude takes in a path string and adds the path to the includes list.

@cDefine and @cUndef define and undefine things for the import.

These three functions work exactly as you'd expect them to work within C code.

Similar to @import, this returns a struct type with declarations. It is typically recommended to only use one instance of @cImport in an application to avoid symbol collisions; the types generated within one cImport will not be equivalent to those generated in another.

cImport is only available when linking libc.
