struct zx_string_view

Defined at line 26 of file ../../zircon/system/public/zircon/string_view.h

This represents a UTF-8 string constant provided by the vDSO itself.

This pointer remains valid and the string doesn't change for the

life of the process (if not the system).

This type exists to be the return value type for vDSO functions.

In current machine ABIs, it's returned "for free" in two registers.

To a C caller, these functions have ABIs indistinguishable from if

they simply returned `const char*` so there is no overhead to

supporting the explicit-length API as well as the traditional C

string API, though it does require writing out `.c_str` in the

source. C++ 17 callers can take advantage of direct coercion to

the standard std::string_view and std::u8string_view types, which

also allows e.g. direct construction of std::string.
