Function getSdk [src]

Detect SDK on Darwin. Calls xcrun --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.

Prototype

pub fn getSdk(allocator: Allocator, target: Target) ?[]const u8

Parameters

allocator: Allocatortarget: Target
