Function std.string.toStringz

Prototypes

immutable(char)* toStringz(
  const(char)[] s
) pure nothrow @trusted;

immutable(char)* toStringz(
  const(string) s
) pure nothrow @trusted;

Parameters

NameDescription
s A D-style string.

Returns

A C-style null-terminated string equivalent to s. s must not contain embedded '\0''s as any C function will treat the first '\0' that it sees as the end of the string. If s.empty is true, then a string containing only '\0' is returned.

Important Note: When passing a char* to a C function, and the C function keeps it around for any reason, make sure that you keep a reference to it in your D code. Otherwise, it may become invalid during a garbage collection cycle and cause a nasty bug when the C code tries to use it.
