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.

Block

On WASI without libc, this is void because the environment has to be queried and heap-allocated at runtime.

On Windows, the memory pointed at by the PEB changes when the environment is modified, so a long-lived pointer cannot be used. Therefore, on this operating system void is also used.

Environ.Block

pub const Block = switch (native_os)

Code

pub const Block = switch (native_os) {
    .windows => GlobalBlock,
    .wasi, .emscripten => switch (builtin.link_libc) {
        false => GlobalBlock,
        true => PosixBlock,
    },
    .freestanding, .other => GlobalBlock,
    else => PosixBlock,
