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.

Init

A standard set of pre-initialized useful APIs for programs to take advantage of. This is the type of the first parameter of the main function. Applications wanting more flexibility can accept Init.Minimal instead.

Completion of https://github.com/ziglang/zig/issues/24510 will also allow the second parameter of the main function to be a custom struct that contain auto-parsed CLI arguments.

process.Init

pub const Init = struct

Code

pub const Init = struct {
    /// `Init` is a superset of `Minimal`; the latter is included here.
    minimal: Minimal,
    /// Permanent storage for the entire process, cleaned automatically on
    /// exit. Threadsafe.
    arena: *std.heap.ArenaAllocator,
    /// A default-selected general purpose allocator for temporary heap
    /// allocations. Debug mode will set up leak checking if possible.
    /// Threadsafe.
    gpa: Allocator,
    /// An appropriate default Io implementation based on the target
    /// configuration. Debug mode will set up leak checking if possible.
    io: Io,
    /// Environment variables, initialized with `gpa`. Not threadsafe.
    environ_map: *Environ.Map,
    /// Named files that have been provided by the parent process. This is
    /// mainly useful on WASI, but can be used on other systems to mimic the
    /// behavior with respect to stdio.
    preopens: Preopens,

    /// Alternative to `Init` as the first parameter of the main function.
    pub const Minimal = struct {
        /// Environment variables.
        environ: Environ,
        /// Command line arguments.
        args: Args,
    };
