Zig 0.17.0-dev (Split by item)

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 library itself.

unwindFrame

Unwind a frame using MachO compact unwind info (from __unwind_info). If the compact encoding can't encode a way to unwind a frame, it will defer unwinding to DWARF, in which case __eh_frame will be used if available.

MachO.unwindFrame

pub fn unwindFrame(si: *SelfInfo, io: Io, context: *UnwindContext) Error!usize
