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.

requiresLibC

Does this target require linking libc? This may be the case if the target has an unstable syscall interface, for example.

Target.requiresLibC

pub fn requiresLibC(target: *const Target) bool

lib/std/Target.zig:2230
