NameDescription
cString A null-terminated c-style string.

Example

writeln(fromStringz("foo\0"c.ptr)); // "foo"c
writeln(fromStringz("foo\0"w.ptr)); // "foo"w
writeln(fromStringz("foo\0"d.ptr)); // "foo"d

writeln(fromStringz("福\0"c.ptr)); // "福"c
writeln(fromStringz("福\0"w.ptr)); // "福"w
writeln(fromStringz("福\0"d.ptr)); // "福"d

Example

struct C
{
    char[32] name;
}
writeln(C("foo\0"c).name.fromStringz()); // "foo"c

struct W
{
    wchar[32] name;
}
writeln(W("foo\0"w).name.fromStringz()); // "foo"w

struct D
{
    dchar[32] name;
}
writeln(D("foo\0"d).name.fromStringz()); // "foo"d
