Prototype

pub fn createNullDelimitedEnvMap(arena: mem.Allocator, env_map: *const EnvMap) Allocator.Error![:null]?[*:0]u8

Parameters

arena: mem.Allocatorenv_map: *const EnvMap

Example

 test createNullDelimitedEnvMap {

    var envmap = EnvMap.init(allocator);
    defer envmap.deinit();

    try envmap.put("HOME", "/home/ifreund");

    try envmap.put("DISPLAY", ":1");
    try envmap.put("DEBUGINFOD_URLS", " ");
    try envmap.put("XCURSOR_SIZE", "24");

    var arena = std.heap.ArenaAllocator.init(allocator);
    defer arena.deinit();
    const environ = try createNullDelimitedEnvMap(arena.allocator(), &envmap);

    try testing.expectEqual(@as(usize, 5), environ.len);

    inline for (.{
