This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

getSdk

Public Function
std.zig.system.darwin.getSdk
pub fn getSdk(gpa: Allocator, io: Io, target: *const Target) ?[]const u8

Detect SDK on Darwin. Calls xcrun --sdk <target_sdk> --show-sdk-path which fetches the path to the SDK. Caller owns the memory. stderr from xcrun is ignored. If error.OutOfMemory occurs in Allocator, this function returns null.
